Hi,

when I would like to check back if a serial a customer provides (11 first digits of course) is a valid one (as in "correctly licensed by MAXON") who do I need to contact?

This is an US customer.

I really don´t want to sell my plugins to grey versions of C4D licenses so is there a way to get confirmation of validity from MAXON somehow?

Thanks

Unfortunatly this currently not possible (legal issues etc.).

The problem is a serial generated by a keygen can by chance match a legal serial.

cheers,
Matthias
