try re-downloading; if you're using the beta it's probably just a stability issue. Maybe use the official version instead?
well, i'll try that, but it seems that most of the time that the error happens i had loaded someone else's save and pasted a stamp into that, and when i left that save or opened another one that the error triggers... im not sure that it's the saves, but possibly the stamps, because i can open the same save and do the same things that would trigger the error on my computer and don't trigger that same error on another computer... basically, the error only seems to happen on my computer... also, im not sure if missing a .exe file from my computer has anything to do with the error... because im missing my run32dll.exe file or something like that...
