PaladinHeart: Yeah it's the humble bundle version. Was kinda hoping I wouldn't have to d/l it again through steam.. 1.7gb you know.
I played it when it was released (the HB version ) it worked back then, I just tried to re-downloaded it to see if they change something, will test in 30 minutes.
Did you check if the "dump" file is a binary one of some sort of human readable log ?
EDIT: Ok just tried, HB version, freshly downloaded and it works fine. I even tried to play part of the first level with no issues (On Win7 64bits / ATI card / Disconnected from the net)
Are you sure you have the latest update of DX and the latest Visual C++ runtimes installed ?
