Launching Python has encounterd a problem. Unable to get project for the run

It would let me put the word problem in the title.

The title is the exact message i get when i try to run/debug a file in Aptana 3.

I have always been able to run Python in Eclipse without problems. Does anyone know what causes this error?

For testing purposes i just created a new Pydev project with only 1 file in it.
