Changing module folder names after install causes silent death of process

[Cryptonic26]

I know I shouldn't be in the modules folder renaming stuff, but folks out there are going to do that, and it causes the application to silently error and close the next time you try to open it.

An error dialog with a 'module not found at {{path}}' before the process exits would be extremely helpful to new and curious developers, and will keep their first experience with the system positive and pleasant.
