WOW Patch 2.0 problem?

[Airlag]

After WOW patched to 2.01 I can't start WOW UI Designer.
I get the error message

WoW Initialisation Error
Der Wert darf nicht NULL sein. Parametername: stream

for non-germans:
The value must not be NULL. Parameter name: stream

I think it has something to do with the patch, because before, I had no problems.
After clicking OK, several features are not available, like browsing the Blizzard UI Files. When I try to open one of my project files, the program crashes.

This is the details of the crash:

Sorry, I have yet to get around to updating the main file with the latest version. You can get a version that is partially compatible from http://www.wowinterface.com/download...usadeBeta.html, that will allow you to start up the designer and you should be able to work with your existing forms.

Thank you very much, it seems to work again.
