The runtime errors are usually encountered when the application has bugs. This is not related to compatibility or anything of the kind. Try to re-install the application or use the Repair option. The Repair option will keep your 3rd party content while fixing the program's application. Additionally, simply restart the application and it should work back. If you could, try to replicate the action that led to the runtime error. If it doesn't happen again, it was a simple bug.
