It Said Invalid MC path selected (-3)

It normally validates the MC directory by looking for a launcher_profiles.json file.

We probably need to adjust this to not look for any files and can use any directory as a MC directory path now…it did not used to be like this, but we are 100% independent of MC launcher now.
