While I have no problem posting their problems here, this thread is mostly for in-game bugs/glitches/etc that generally occur for everyone, not just specific problems. You say it won't run on your 9800gt, and someone else just confirmed it doesn't work for them either, so it must be a driver issue.
If you really want to try this game, search for another thread related to 9800gt's or make a new thread.
Here are two threads related to 9800gt cards.

The second link will go directly to a post by someone with a 9800 problem and has a small tutorial on how he fixed it. That's all I can do, otherwise you'll just have to wait until Frictional releases another patch.
