Drum stopped turning

I pretty much followed the instruction sheet that was included with the new drum belt BUT, this should be added in step #2. "If working alone" Before removing the front door panel: A)pull down lower access panel. B)Support the weight of the drum. (This can prevent damaging the rear drum seal!).
Also, instruction sheet step #5 should read: Route belt through the idler pulley bracket (by pulling side of bracket open enough to insert belt) and then around the motor pulley.
Step #7) A putty knife with the end rounded off works best!
Thanks!
