well my tmt3 worked great before i took my 5770 out and went back to using the 4200hd card,now if i run it it says programme has to shut down,so i unistalled it and installed it again and it works fine if i use version .120,but if i install the updates it closes down again,funny enough i tried powerdvd and it works on a old version but if i update it to the lates it closes down,any ideas please,ive installed my drivers again,might have to reformat,thanks
