CDJ-2000 Nexus - E-7206: Auth Chip Error

Hi,

I just got home from a vacation and wanted to start playing on my CDJ 2000 nexus and DJM 2000 nexus but when I booted the CDJ it gave me an error named: E-7206: Auth Chip Error 

I've googled around trying to fix it but there's no one who seems to be able to fix it. I've already tried to factory reset it and it's still the same, aswell as updating the firmware which currently is 1.22 and should be the latest.

If there's a fix it would be great instead of going to the shop. I haven't changed anything at all with the CDJ and I don't know how it's not working.

Thank you,

Jacob S.
