I killed the program with task manager (to save time after getting incompatable star sign for the character I intended to make) and now every time I start it, it closes instantly. I recall there was some issue with perc file when doing that and it should be deleted, but this version of ADOM doesn't seem to have any other files than EXE and deleting and "reinstalling" it didn't fix it.

Good thing this is just a work computer and it doesn't really matter that much. I think I might be able to fix this with a system restore since
none of the thing done with this computer really matter anyway, though I might not be able to do that without administrative rights, which I don't happen to have.
Is there any other way to fix this?

I suppose I could just play JADE then, though I feel so lost there (why couldn't it work and look more like ADOM?)
