Reply to Replacement Jogwheel Platters

Hey guys, I bought a used VCI100 a few months ago online. Everything has been great, except that the previous user had overtightened the metal touch surface disks to the clear plastic platters. The holes are now either cracked or stripped so the metal disk keeps coming loose- making my jog unresponsive to touch. The problem seems to be getting worse and happening quicker as time goes on. Anyone know where I can buy some replacements? I already emailed the store, figuring they may have some due to the refurb program, but no dice there. Thanks
