you should check your clutch fluid. if it's low, just refill it with DOT 4 brake fluid. if you're not sure where the reservoir is, just check your manual. this happened to me a couple months back. but you better watch out. about a year and a half ago, one of my flywheel bolts popped loose and i couldn't disengage at all. me and my bros had to take out the tranny just to screw in that one bolt. it was a pain....
