I have used the 30 day trial. I am going to do the $49.00 deal to get Premiere and other apps. Premiere works well on my Mac. But Horrors! I suddenly realized that the project I am editing on Premiere is not finished. If I do the $49.00 deal will Premiere reload from scratch again and wipe out everything I've done. Say it ain't so...please say it ain't so.
Save the project file and all of your media and presets.. (And back it up, too.) It will open if it was created in the same version.
Just be sure to subscribe before the new version comes out, or it may have problems opening with CS Next, expected to be released about May 6, 2013.
