FilmGuard cannot scratch a print. That simply is impossible. The scratch has to be coming from either excessive tension on the cleaner (not possible with a Strong platter), bad media (doubtful), bad bearings in your sound drum that is causing it to freeze up, a defective cleaning machine, or an operator misthread.
Can you spin the sounddrum by hand with minimal effort? When you let go, does it continue to spin on it's own for awhile?
What kind of media are you using?
Strong platters do not have a keeper roller on every roller in the takeup chain. Many times I have walked into a theater running and the film on the takeup path was dragging over a roller's shaft instead of being ON the roller.
Are you SURE that the media advanced during the show? Far too often people blame bad media or something else on a scratch, when it is the person who loaded the film cleaner in the first place who did not tighten down the thumbscrews, or properly secure the head of the media to the takeup shaft, or the cleaner is missing (or cannot grab) the takeup cores. Heck, for that matter if your cleaner has ever been dropped and the main flywheel is tight in the least bit, Strong platters do not have enough backtension to force them to spin. The result is the media does not advance and you scratch the print.
There are a lot of possibilities here. Give us all the info you can...especially a detailed description of the scratch location, if they move around or jiggle, vertical/horizontal/diagonal, etc.
