Thank You for your response.
I could not copy -paste the error log, and a didnt want to write it down, i tought the other error messages were enough. Today I tried to run the game again, unsuccesfully, but the error log didnt pop up anymore. ??
I forgot to mention that a bought the game via steam. A tried to add the latest upgrade patch to the game but i received the message, that the game wasnt installed. I dont understand this, either.
Ok, I keep trying, anyway thanks for the response.
