Hi, I've borrowed a friends Sizzex Big Shot Pro and after 10 minutes gentle use the turning metal shaft (that comes from the handle) has come away from the casing. One of the die templates is now jammed between the rollers and I haven't a clue how to fix this. Is this a common problem? Does anyone know how I can attached the shaft? It doesn't make any sense as there is no give to push it back in. Its as if it's 1/2cm too short.
