Ok so i went to change the nuts on my rear wheel, my old ones were getting stripped. I thought this would be a pretty simply task, apparently I was wrong. The old nuts came off fine, no big deal. I go to put the new ones on and they refuse to move any further than a spin or two, and now one is stuck and wont come off. So at the moment my bikes rear wheel is sitting next to me with a single nut stuck on it.

Help?
