I just lost 5 hours loading, then unloading 5.1, then reloading 5.29.
There seems to be a problem loading onto 64 bit machines and also losing the database registry(???) known about since last week.
I wish they would have posted that.
I thought that I had held off long enough , but I should have waited a little longer.
So goes the world of beta.
I hope they clear this up soon, complete meaningful use and get the pm done.
Just my Christmas wish, Santa.
