Most likely there's something wrong with your system. As far as I know, all released tex tools share the same code for loading tex files.
I think it was written by Steve Mitlehimer (or something like that)
Anyway... that could explain why you are getting the exact same error with all tools.
Try to open a tex files with this:
[
files.vadertrophy.com]
Execute the exe file and drag any tex file onto the opened window.
If it shows up, then I have no idea what's wrong because i don't have the code that all other tex tools use.
If it doesn't, then it's probably because a DX error. Then try to reinstall DirectX.
I'd rather have a bottle in front of me than a frontal lobotomy
