I solved my .dll troubles while no solutions on the downloadsite worked and came to share my insights.
If someone like me has their systems Unicode set to Japanese for.... reasons i suspect are also present in the playerbase of this game, the game won't start and show a .dll errormessage to check for viruses and reinstall the game. All suggested solutions even deleting the F1AltEnterF12.dll file didn't work. After some time I found that the japanese unicode was the problem and changing it (in my case back to German) worked. Maybe this info shoud/could be added to the FAQ on the downloadtab.
Nice game so far I enjoyed the relatively few hours i put in until now quite a lot already. A good challenging RPG were decisions you make in a few seconds matter to a degree i haven't seen in any other game so far.
I hope this helps a few people.
