Running from a shortcut: run-time error '9'

I'm trying to run an exp file directly from a shortcut. The pop-up asking for the subject ID comes up, but when I hit okay, I get the "Run-time error '9': Subscript out of range" error. When I run the file directly from Medialab, I don't get this message. I'm using Medialab v2008.
Nevermind, I discovered the problem. I had mis-specified the path for the shortcut.

Thank you for the update-glad you were able to figure it out!
