SYMPTOMS

CAUSE

The UMSID is the unique identifier that the login-based licensing website uses to recognise your machine.  The UMSID depends on several bits of information about your machine, including the hostname, IP address and SystemID.

When an activated machines checks back in with the login-based licensing website, the website checks that the UMSID in the license request matches what is stored for the currently activated devices.  If the UMSID of your machine has changed for any reason (this can happen with some network or hardware changes) then the machine will appear to not be valid and you'll see the error above.

 

RESOLUTION

You can fix this problem by reactivating the license on the machine by doing the following steps:

  1. First of all please deactivate any devices that your entitlement is registered to by following the instructions below:

    OSX: /Users/<USERNAME>/FoundryLicensing/
    /Users/<USERNAME>/FoundryLicensing/

    (Where <USERNAME> is your log in name)

  3.  Reactivate your log in based licence by following the steps below:
