space bar and play button not working
 

Hi all, I am in ppro with prospect hd. I tried to convert some 60i footage to 24p and when I brought it in to the project, the space bar and play button quit working. I can hit control and space and it will work. I opened a new project and imported one cineform file and it still doesnt work. Any thoughts? I have opened premier with the shift key held down which I think is supposed to set to default settings but that didnt help either. Thanks TAG
