Hello, I'm having a similar problem with the trial complaining about a clock mismatch. I messed with the MoI beta for a couple months on my previous computer-- a few days ago I got a new Macbook Pro (completely fresh install, no migration) and stuck the last beta (Jun 1st release) on it, which I think I opened once. I'd really like to give the trial a shot; any chance of some kind of workaround? Oh, I am running Mountain Lion DP4, so perhaps the issue is related to that. Anyway, I'd be happy to help diagnose; I'm eager to check out the final version!

Thanks,
Will
