Hi.I would'nt consider myself extremly experienced with Premiere Pro. But I edited a shortfilm for a school project. I have put many hours into the editing of it but today when I had edited for around 2 hours i realsied that the window had frozen, but everything else in the program worked. I decide to press "Program Sequence" above the window and press close. Suddenly the workspace was empty and the window aswell. I got surprised put thought that i should restart the program. Then it asked if i wanted to "Save the changes" and to not lose anythigng i had worked on the last 3 hours i pressed Save. When i reopened it was'nt frozen but the workspace was still empty. What should i do or am i screwed?
