Error in guiminer on startup

[Fill]

When I try to run guiminer, I get the following error message:

Errors occurred
See the logfile '[path to logfile]' for details

This is what shows up in the log file:

Code:

I'm running a Windows 7 machine and guiminer-20121203.exe, as administrator, with a Radeon 9800 card and OpenCL installed.

I tried searching around the forum, but couldn't find anyone with the same error. Hopefully it's just my search skills that sucks, and this error is known

Radeon 9800 card

Here is the problem.

A 10 year old card is not ok. OpenCL?  Lol

Darn, I was hoping I could use a couple of older machines given to me for free. Oh well, thanks for the heads up!
