Amnesia doesn't save my game

[corban]

Try removing the current Amnesia folder in Documents, it could be that the write permissions are incorrect due to the demo having created them and now another application (the full game) tries to write to it.

I have noticed that this problem occurs only with Steam users but we have not found a solution yet. Try to close steam and then start it again using administrator rights (right click > run as administrator). See if that helps at all...

Nope it didn't help either :/
