For ethminer: do not use the "-U" switch, that makes ethminer use CUDA which is for nvidia cards only, instead use the "-G" switch which will make ethminer use OpenCL for your AMD cards.
Updated... still no go
What is the ethminer command line you used now, and what is the new error?
This is what I just used..
ethminer.exe --farm-recheck 200 -G -S us1.ethermine.org:4444 -FS eu1.ethermine.org:4444 -O 0x0fAea99B63369dc4eaeB50217e1DED7FDb91F551.Miner1
There isn't an error now. It's like the the program runs, but doesn't start mining.
