The clicking is probably the clutch. It is slipping as the rusted gears are making the system act as though the slide is at the end of it's travel, or has hit an obstruction.
I would get an aerosol can of the penetrating lubricant of your choice, and shoot it in there.
If room permits, tapping it with a plastic headed hammer etc. may be enough to free it up. If not, a drive may very well do it. It all depends on just how "stuck" the gears are.
Good luck

Spend $5 for a can of aerosol penetrating lube and save $400 or $500. Spray everything down. let it set a few hours then get some one to push the switch while you try to help it get started moving. Be careful though those gears will eat fingers. You also might want to check to see if the slide seals need some 303 Protectant or something similar as they may be stuck also.
