Got an error after registered.

[vanquished beliefs]

after  i registered i kept getting an error message saying an access violation at address ..........
i almost never got this before registering. im pretty sure its b.c of it.
ive reinstalled soldat, messed around with the config but nothing seems to work.
but if i dont play it in fullscreen its fine, but if its not in fullscreen i cant play well.

any help?

Are you sure that the key you used isn't a crack of some sort? Otherwise, you wouldn't be seeing that message.
