After much aggravation I finally figured out that my constant crashes when saving a project seems to be due to the tempo map together with audio. The project was originally created in 9.0 with a tempo map created as well. Trying to save the file in 9.5 would crash the program. I then copied each part out and pasted into a new project. For the tempo map I copied all the points and pasted them. Then I could save the project. If I exported the original tempo map and then imported into the newly created project the project would crash when trying to save. I went through all my other 9.0 projects and found that if it was all midi then they saved but for projects with audio saving would crash the program if there was a tempo map already created in 9.0. Strange. The only solution was to copy parts out into a new project and save. I submitted a ticket but no response after a couple of weeks. I guess they are busy with all the other bugs.
