Cannot get Pro Tools to run

I cannot get Pro Tools to run properly...

I have tried and tried to get it to work and keep getting this (or similar) error messages:

Could not create a new document because Assertion in "/Volumes/Development/139084/ProTools/DFW/MacBuild/../Views/UMenu.MacOS.mm", line 1549.



please help me as I really do want to use this program...

when I searched for that file it was not there so idk how to resolve this issue.

I have tried uninstalling & reinstalling it but to no avail...
