I have just installed and tried the Ultimate Edition Upgrade button. I get a message to rerun the script and check for internet connection. Rerunning just results in the same message.
I am on dial up and am 54 miles from the modem at the server. This gives a speed of 4.4Kb on a good day. Today is not a good day. Speed is about 3.2 Kb.
Just thought that I should through this out there for those of us on dial up. Developers don't think of us very often.
