Have you cocked the shutter? If not then this was your problem. If yes then the problem lies elsewhere...
Not cocking the shutter before loading the film wonīt do any harm to the camera, but since cocking the shutter and advancing the film is one operation you will end up with only 11 exposures if you donīt do it. I hope that this was the case and there is no serious issue with the camera... If you have put in a film without having the shutter cocked you can however do it by pressing the double exposure button. This will cock it without advancing the frame.
