I bought a treadmill from a friend of mine. It's hardly been used and is in really good shape. The only issue I am having is under the front roller where the belt wraps around is a plastic/rubber liner that wont stay put. Every time I get on the treadmill it slides over to the right and ends up all clumped together and grinds again the end of the treadmill. I was on it Sunday and a huge piece of it came flying off and it was burning hot.

I have tried and tried to get a hold of Proform with no luck.

Any ideas?
