.lock file creating and deleting (Cant open projects)

Hello,

I can’t seem to open any storyboard pro files, when I try it creates a lock file, it loads the project up and then the file vanishes and the software goes with it.

I tried an older file just to see if it would do the same, I got an error saying it couldn’t create the .lock file and then the software loaded up and closed itself again.

Please Help
