Vista - Logging in limbo with Reqiured Beta "Upgrade"

Required "upgrade" to Beta?!?!
To add to the litany of complaints, this morning I had the dreaded message
waiting for me - "You need to update". So, reluctanly, I did. It seems to
have installed. It took ~30min to log in. I thought all is well. Not so, it
has fallen off and now it's stuck in another interminable "Logging in.
Waiting for server" limbo.
Some notes:
- For a required update, it is incredible to be greeted by a welcome screen
that announces it as a "beta" application. You're forcing everybody to update
to a beta product?!?
- Pretty extraordinary that there is no sign of a changelog anywhere. We are
told that this update will improve stability. However, the first thing I
experience is the same problem that's plagued the program in recent months...
Are there actual improvements somewhere, or just dropped features/support to
accompany a slightly different GUI?!

I am going to keep an open mind about this program for a little while
longer - at least until I give the Devs. have a chance to right the ship
during this "upgrade" phase. But if the problems continue, I suspect you are
going to lose users in droves - to other programs, such as PowerFolder,
etc...
