The error you are getting is because Pro Tools can't load another piece of software it needs in order to run. I really can't tell what that component is from the error message, but something must have changed.

From the screen shot, it looks like that computer is used for more than just Pro Tools, so is there any program that was just installed or updated?

You may either need to remove whatever was just installed, or you will need to uninstall and reinstall Pro Tools.
