My Pro Tools 10HD is getting me crazy. Every time I load up my session it scans thr plugins and crashes. I also get this error often, when I start playing, it says "Error -9507 and -9031".

 

Did you tried to temporary move the plugins from the main location to another folder and run PT to see if it crashes anymore? Maybe there's a problem with one of your plugins and not with PT.

 

This might help with your DAE errors:

"There can be many events which may have resulted in the system files errors. An incomplete installation, an incomplete uninstall, improper deletion of applications or hardware. It can also be caused if your computer is recovered from a virus or adware/spyware attack or by an improper shutdown of the computer. All the above actives may result in the deletion or corruption of the entries in the windows system files. This corrupted system file will lead to the missing and wrongly linked information and files needed for the proper working of the application."
