Switching Themes forces the app to crash

[texium]

I switched my theme away from vista or hybrid and now the app doesn't even open. It will pop on in task manager then just die. Not sure what to do, heres the log from the bug text file:
Version R 2.14f
Traceback (most recent call last):

I just fixed an update, maybe that was the problem.
Reinstalling the application will probably fix it.

In the UserData/__config__ folder, there is a file = lk.pk2, rename it to lk.pk2.old, and launch the program again.
