I had the same problem with the same camera two years ago. However, nothing was wrong. It happened because I simply moved the film-advance lever approximately 30 degrees and then I stop it without any logical reason. When I tried to move the lever, it looked like it was not possible to move more. I carried the camera to repair but the person who was working in the store simply pushes the lever forward and it moved perfectly. I recommend you to try to move the lever carefully, and probably you will have your camera working perfectly.
