I am unsure about your personal treadmill, but, have you started with the easy things:
Check that the cutoff cable is in place?
The contacts (if it has them, some are magnetic) of the cutoff are clean and free to connect?
If they are ok, does it sound like the motor is trying to turn?
Are there any burning smells?
Have you checked for a motor fuse in the treadmill itself?
I hope that gets you a little closer to finding the problem.
Edit, i didnt see the full question, sorry. Sounds like there is a motor fuse gone.
I have found the service manual here if you need it:

there should be two screws one on each side of the belt in the back of the treadmill (you may need to remove the side rails (theres one on each side of the belt) to see them) those screws will tighten the belt. note: you must be carfull that the belt is tightened evenly. livestrong.com is a great website if you need help wih this. good luck!
