Everytime I try to start L4D it says my driver is out of date.

Which is weird since I just updated my driver a few days ago, maybe I'm not installing it right or something, but after numerous reinstalls it keeps saying it is out of date.

I have a MSI HD r4670 and I just downloaded the newest driver off of the ATI Website which is version 8.591.0.0000, but L4D keeps saying my version is only 8.14.10.647

Maybe you have a beta driver which is not being recognised properly yet.

Says I have an outdated one too, I have cat 9.3 Not that it means anything.
