License Key issue

Hello all

I have recieved a license code from my account manager but the OM install is refusing to accept it.  This serial number is generic, what would be wrong with my license code?  Is it being used elsewhere?  is it platform dependent - unix vr windows?  something else?

Error: Failed to update the Operations Manager license: Serial number of the license key does not match this system's serial number.
