11.3b8 works just fine. The only difference between that and 11.3b10 is essentially TiVo set the units to never expire, hence why a program cleverly written called "Ticketmaster" by one of our talented software people is automatically installed and run on a machine with 11.3b8 and not on 11.3b10 so that it "keeps alive" units still on 11.3b8

For everything else it is exactly the same from all the testing we have done.

For any machines NOT on 11.3b8 or 11.3b10 or with a failed hard disk there is a pre-installed 11.3b10 image that can be restored with WinMFS available on request.
