Hi , It's strange but there is no fresh files in mentioned folder. Around february-april last year I ve the same problem with Underrail - but back then Xna 4 solved it and in the Documents\My Games\Underrail\ there is only data from that time (some saves and crash log) i've deleted it and reinstalled the game (thru Steam engine) but nothing appeared out there not even "Underrail" folder. I've searched for any other crashlogs on C:/ or even checked files by modyfication date but there is nothing usefull. In the meantime I will try to install demo once again to see if it will create any crashlogs. I can provide you withe old crash log content which is:
