Liftmaster 3800 Reversed Opening and Closing

I have the liftmaster 3800 opener and tried to install. I have it all connected properly, wired up, and it will open and close the door ok. However the opener is reversed as far as opening and closing because the cable falls off of the front of the drums on the torsion bar instead of the back. I understand that this is a common setup for low headroom garage doors (see this website for an example http://ddmgaragedoors.com/diy-instructions/replace-garage-do . . .). All you guys that do the Liftmasters, is there a way to switch the opener to flip the open and close cycles around? Currently if you break the beam of the obstruction eyeballs, the door "reverses" but closes instead of opens like it should. Plus it detects the full open position as hitting an obstruction and automatically closes. I need to fix this somehow. I spent days getting an outlet to the opener and installing this thing!
