I have a W7 Home desktop, an XP Laptop, and a recently acquired W7 Home laptop. I cannot make the W7 Home laptop (New) to make the other 2 trusted, and on the XP I can't make the new one (W7 Home laptop) trusted. Message says each PC is temporarily unavailable. Program is McAfee Total Protection and I have 4 licenses. No other AV software installed. Any help or ideas?
