Project is frozen in 9.5 but ok in 9 and 10

got the dreaded UAD out of resources when trying to add a plug in 9.5. Spinning ball so had to force quit. Couldnt get it to open in 9 but it did in 10 so i pulled out some plugs down to 77% and saved under another name. New name still wont open in 9.5 but now it opens in 9 and 10. would love to know why…Using an Octo Satellite for the uad.


Could you try to Backup project, please?
