Messed up window. Need help.

[Stepside65]

The right window on my 63 GMC is broke and I have no clue how to fix it. I made the mistake of rolling it down once. Now I can't for the life of me get it to roll back up. I took the inner door panel off and tried to coax it into just raising and staying there but it keeps binding halfway up. I searched around and still couldn't figure out what it was hitting on. The window glass is up now. Held up by a screw driver to keep rain out of the cab. The mechanism that holds it is lying in the bottom of the door right now. I need to fix this thing so I don't end up breaking the glass. Has this happenned to anybody before? Any help is greatly appreciated.
