I have went down for a day to upgrade drivers and upgraded my HD5850 drivers, as well,  and now all I am getting from GUIminer is this error

So does any one know if the new catalyst drivers are causing an issue or knows of a fix, it would kindly be appreciated. I have tried wiping the drivers and reinstalling from scratch again 2 times already.
 thanks for any assistance

What kind of system - Linux, Windows, MacOS - do you have?

windows 7 64bit .. sorry forgot to mention that

try reinstalling GUIminer I belive it has to recomple it's kernel

if not, reinstall windows :(

i heard there may be some driver issue, try downgrading your video card drivers again :)

Diablo miner FTW!

I would try cgminer, I like it a lot on windows 8.
