I try to open some V7 projects, they simply do not open... they stop at 1% and don't go any further, V7 takes a while to open them as well but still... V8 just stops...

I only tried the one I was working on when I upgraded to trial, and I had no issues.

some of the files work (the smaller ones) but these have large media bins with lots of project files and they just wont open...

I opened a few V7 files tonight....they worked fine...but they were fairly small files....
