Hi

. . . . movie edit pro 17 . . .

What is the full name and version number of the program - see under Help, About.

. . . . Can I rotate more than 1 clip at a time? . . . .

Yes, select them all first then apply the rotation effect.

. . . . When I open up my session back up, . . .

What do you mean by this -

1. are you saving the project, with or without a different name, before exiting the program and then reloading this?
   
   or
    
2. reloading a backup project the MEP creates at regular intervals ie one that has _BAKn.MV_ as part of its name where n = a number between 0 and 9?
