So, I can successfully mine with my 6990 card using CG Miner version 2.10.3, but anything past this version of CG Miner just fails right before initializing the card for mining.

Card Info - HIS H699F4G4M Radeon HD 6990 - http://www.newegg.com/Product/Product.aspx?Item=N82E16814161366

Driver Info - AMD Catalyst™ 13.2 Beta Driver - http://support.amd.com/us/kbarticles/Pages/amdcatalyst132betadriver.aspx

OS - Windows 8 Pro

Since this card is a little bit older, should I be using an older more stable version of the AMD Catalyst driver, or will that result resurfacing old issues that the newer drivers have fixed?

Additionally, in the same vein I'm unable to do any --scrypt mining with any version of cgminer using my current driver setup because CGMiner fails right before mining starts.

By fails I mean it brings up the generic windows, "An unexpected error has occurred." dialog and CGMiner closes.

I'll try to update this thread later with my actual command line from my batch file, but I'm fairly certain that's not causing any issues.

Uninstall only the AMD-APP-SDK installed with the driver, and install with a custom install "AMD APP SDK CPU Runtime" (deselect developer,kernel analyzer,samples,etc)
from "AMD-APP-SDK-v2.8-Windows-64.exe".
