My Max for live is Stuck?

    Dec 11 2013 | 1:14 pm
    When I try and open one of my Max for live projects it gets stuck.
    I drag the patch into Ableton and it then comes up with the "open location" tab, I then go to the file and click on it but its greyed out and cant select it?
    It was working before lunch and now it dosnt, ive tried the patch on a different computer and restarted my computer, but nothing.
    If all else fails i will just have to build it again from memory and hope for the best.
    Has anyone had this problem before?
