Well, I didn't have chance to ask the Tech Support guy anything else, and this is off topic, but has anyone else encountered this problem:
When doing an Escort quest or if you click on someone else's NPC, the game will crash out to the Desktop with a Windows error. It usually occurs when trying to Cure them or in the case of Escort, clicking to make them stop. I've tried reporting this to a GM via GM Call in PoL, but she refused to acknowledge it was a problem with the game and that it was my PC at fault.
I know 4 or 5 people who have had this exact same problem and each of our PCs can't be identical, yet SE refuse to see it as an error on their behalf. Last Escort quest I did in Eldieme Necropolis, 3 different people all dc-ed due to this problem. I was told to turn my effects filters off by the GM, and when I replied they were already off, I got: "I can assure you it's not a problem with the game code. I suspect it is an error with your graphics card, that it cannot handle the effects. If you have any further problems, please contact Tech Support about PC compatibility issues."
