Urgent! Need Help in Minneapolis area!

Hey all,
I've got a Rockler store in Maplewood, MN that is having trouble with their demo unit. We are pretty sure they just have a stuck roller, but the store employees don't have the time to work on it. They are supposed to be running a demo on Saturday, but no working unit. Anyone in the area able to go help them out between now and Saturday morning? We can walk you through the repair on the phone, even if it's outside of our normal hours. I'll make it worth your while.
