Avid XPress Pro v4.5 I am having probalems with this program all of a sudden. It has worked fine for a year and then I don't even use it for a coupe months and I come back and its all wonky. It still seems to edit alright, the problem seems to be playback. For some reason when you play something in either the preview or edit window the image goes black like there isn't any video there (although there clearly is and on the timeline it IS selected to show up). It does play though and the audio can be heard just fine. Anybody have any idea what could make it do this all of a sudden?
