that is usually from sgminer - usually a compilation error - and usually because it wasnt compiled with the amd sdk / app ...

BUT - it could also be due to the drivers you are using on your os ( assuming its windows ) ...

though like i said earlier - its 'usually' a compilation error due to missing sdk components ...

ask wolf - if it actually is his miner - as he is a brilliant dev and will help where he can if he is not busy ...
