i have a ATI HD5450 (1GB DDR3) and i cant get it work with pyrit at all !

ive installed the correct drivers (from ATI website)
but when i go to install cpyrit_stream, it also installs the ati-driver, witch dont work, and stops startx from working.

ive tryed to compile it manualy and it just has a bunch of errors.

ive bin at this for a week, and am stuck as hell of what to do. ?

Could i have a "Stupid guide to installing ATI-stream" to get pyrit working please ?

PS pyrit works just fine but only has:
