Had guiminer running 45mhash on my GTX 550ti
Switch cards to a gigabyte ATI HD5770 and I can seem to get it to work.
It says it has connection problems. I downloaded Sdk and the OpenGL and I have no idea how to set this up.
The GTX 550ti just worked when I pushed start mining however the HD5770 does not.
I would be supper appreciative if someone could please explain how to set this up. It can't be that difficult as there are a lot of people using ATI cards. I have been reading for hours and all I could find what what I need
To download and not how to set it up.

Thank you soooooooo much,
Dan
