game crashed 3 times in the last 30 minutes, is there a fix for this?

As much as I love Risen 1 the part 2 is so bad. The fight feels really random etc. Also I tried to sneak into barracks and it just wouldn't work I had to google out you have to roll in. Anyway feels too buggy and bad. I wished they just stayed with Risen 1 mechanics....

new topic because it seems a little different; I have no risen 2 folder in local roaming I can't install nvidia physics; I already have a newer version

ahoy, fresh new player here! last month i finished risen 1 during my journey to clear that dreaded steam library backlog, and this time its risen 2 that needs a playtrough! first of all, ive read some complaints about this game beeing inferior to the first one, but so far i am enjying it for what it is. not a huge fan of john risen not beeing able to swim (seems unwise while sailing on a ship and all), and his general make-over compared to the glorious baldness he had in the first one, but whatever. now...

The game doesn't launch at all. All I see after launching the game program is the "Risen" logo for a second or so and then it disappears and nothing. Does anyone else have this issue?
