Premiere Pro CS4 Sequence Error? (Timeline Window says No sequence, Program Window says no sequence)

Hey, I was trying to edit a bunch of .mpg files together, in a new project file, in a sequence 01, and all the primary editing windows came up, and while I can easily get the source window to recognize sequence 01, both the timeline and the program window say no sequence and dragging sequence 01 or any of the .mpg videos does nothing.

Since I can't even see the timeline of this I can't edit, so if someone could help me as soon as possible that would be great
