Changed belt on GE electric dryer and now it makes like a rubbing noise (like metal on metal). Can someone let me know what to do?

The drum rides on a set of rollers and you had to lift the drum off to get the belt on. Sounds like it is not sitting in the correct track, I'd recehck my positioning of the drum on the rollers. If it were a belt noise I'd say belt dressing or bar soap but not for metal to metal.
