I'm running ZDT 0.5.2 with JRE 1.5.0-09. When I select the Categories tab, I get the following
error message: Unable to create view: Plug-in "net.sourceforge.zdt.flashcard" was unable to
instantiate class "net.sourceforge.zdt.flashcard.views.CategoryView". Please note that I had not
installed any previous version of ZDT prior to 0.5.2. Any suggestions, anyone?

Is this the first time you've run the program? Are you running the Windows version? Try running
again and when you see the message, click on the 'Details >>' button. Then please use copy/paste
and PM the resulting error message that appears.
Usually this message occurs when you run two copies of the program at the same time and they try
to share the same database file.
Thanks!

Thanks for looking into this. Yes, I'm running this on Windows XP. Here's what I clipped from

Just uninstalled 0.5.2 & installed ZDT 0.6.0. Unfortunately, Category view is still broken. Here

Actually the error message means that it can't find your user database file. In the program, go to
Window > Preferences... > Database, and you should see the directory it's trying to look for your
database file. Go to that directory (via windows explorer) and see if you have the files
user.script and user.properties in there. I suspect maybe you don't have permissions so the
installer could not copy the files to that location? If that's the case, let me know and i'll send
you the files you need.

Chris,
Both files you mentioned, user.script and user.properties are in C:\Documents and Settings\zdt,
just as it is indicated in Window>Preferences>Database. The files are obviously there, but
Categories view still does not work. Also, I am on a stand alone machine. There is no
administrator, and the folder system pretty much have all the Windows XP default settings. Thanks
again for checking this out. Let me know if you have any more ideas what it may be.

Thanks, Bogleg, for figuring out why Categories View was not working. I am posting this brief
description just in case someone else has a similar problem:
I installed ZDT 0.6.0 and JRE 1.5.0_09 on a Windows XP / SP2 Tablet PC version OS. For some reason
the required file user.script was installed on my system, but it was empty. To see if you have the
correct user.script file, check the following:
In ZDT, goto Window>Preferences. Highlight Database. You should see the sub-directory or folder
where your user.script file is kept. Using Windows, go to that folder. (eg. mine is at:
C:\Documents and Settings\zdt) Highlight the file user.script. Right click and select Properties.
If the Size is 1 KB, you have an empty user.script file, and this is possibly why Categories View
is not working on your system. Drop Bobleg a line. I am sure he'll gladly send you the correct
one. (The correct file size for user.script should be around 108 KB)

same problem here. I just "upgraded" to 0.60. I get the message:
Unable to create view: Plug-in "com.digitbit.chinese.rcp.flashcard" was unable to instantiate
class "com.digitbit.chinese.rcp.flashcard.views.CategoryView".
My user.script is 154Kb
Help is appreciated!
>>>>>>>>>>>>>>>
(10 Minutes later, playing with ZDT in utter frustration.............)
Whoops, now THAT was fast!
After I did: windows>open perspective>others... ..and chosing "ZDT" it was OK and seem to work
fine now.
I will not delete my question since it may help others, hopefully. BTW, Great program!
flameproof -
Today I installed ZDT on another Xp PC. Same problem, same solution:
start ZDT>windows>open perspective>others... ..and chosing "ZDT" it was OK
Difference: this time it was fixed in 3 seconds.

Just a remark on this issue: Windows users usually don't have r/w permission on directory
"Documents and Settings\", this may be part of the problem. zdt should have placed the reqired
files in folder "Documents and Settings\
would be even more elegant if zdt would place its files in a folder named "Documents and
Settings\,username>zdt\" which is the desired convention used by almost any modern Windows
application.
Btw: I'm using zdt under Windows Vista RC2 5744 without any problems - and I am very happy that I
have found this program ...
