Moving a project from Premiere Pro Tryout to Full Version

Hey all -

I've been working for quite a long time (well, 30 days, but there were
a lot of hours put in ) on a project in Premiere Pro Tryout, as got
from the official site. The tryout expired, and so I've had to move
onto the real thing - I went to open it in the full one, but it gets
half way through and says it can't open it. Now, seeing as I've got no
access to the tryout, I'm a bit stuck.

I'm going to try and install the tryout version on a friend's
computer, and see if I can mess it with it, but can you actually "Save
As" the later version?

Any ideas would be much appreciated - thanks in advance,

Jon
