PT 6.4.1 Mix & Access Virus..? (Red or Indigo)

[Citrin]

Hey Guys,

I've been digging around the net trying to get a clear answer here. I just purchased and old Mix system and I can't seem to get the Virus running.
Reading through the Digi literature says Virus Indigo will work on my system so I've purchased the iLok asset and installed the plug but it wont launch. Do I need to purchase the old Virus red TDM plug and asset and if so where can this be downloaded? It seems the Virus Red compatibility info has vanished from Digi's sight?

Anyone using an old Mix system and running Virus with no issues..? And if so what am I missing that I should know to get this plug up and running.

Thanks for your time..!
