I've been trying to play Rollercoaster Tycoon 3, Platinum Edition with the latest patch but the game keeps crashing and faulting "Hssrv.dll". I'm using Windows 7 64-bit, which I thought might be the issue. But there seems to be a number of people able to play the game on the OS without problems. I tried different compatibility modes, but it seems to cause the crash even faster. Usually it crashes in 5 minutes or so, but once I was able to play for about an hour before it did. I googled "Hssrv.dll" and it seems to be related to some Asus Xonar sound card, which I do not have. I do have an Asus P6T motherboard though and wondered if they were related. I also have 2 GTX 285's setup in SLI, and thought maybe it didn't support SLI and disabled one, but that didn't help either. Any ideas what the issue might be and how to fix it?
