catastrophic failure if directory is not set correctly

[ryangroth5]

If the following directory (Game R:\teknoparrot\UserProfiles) does not exist, when you try to enter this menu, launch box will throw an exception and quit out with no option to correct the directory. 
I'd prefer the program allow me to remap the directory or show a little error icon next to the problematic directory and not just quit to the void. 

 

Thanks,

Ryan
