Opening Project made in older version of TGB

Hey guys. A couple years ago, I downloaded the demo of Torque Game Builder (don't remember what version, but it was an early one) and created some simple games. I just bought the Indie Pro license and I'd like to pick up where I left off. Sadly, I can't figure out how to open up my old game projects in the latest TGB. I have all the folders from my old install. The latest version of TGB wants to open *.t2dproj files only, but I can't find any files like that in my old game folders, and when I try to open other files (like a few t2d files I find) as projects, it doesn work. I tried creating a new project and opening a single level, but, of course, none of my graphics are in place.

Any ideas? Please help!

Thanks,
Benj
