I only download once. I haven't seen it locked to a particular customer...yet. Trust me, it happened when I was on site to do an upgrade and I was a tad upset to say the least. Luckily I was able to talk to someone at Optus that pointed me to where it was now. Good luck with that lawsuit. The EULA makes that a non-starter. What I can't wrap my head around is WHY the SL series get free tech support and assurance and we don't. It boggles the sane mind. I am now going to every customer that lapsed on SA as we speak and getting them on it because the writing is on the wall.
