Hi JoeJ
Your trick works

After I have tryed 3 times, I have to do it very fast before the program crashed, the program started up like after a new install. I typed in my username and password and everything looks fine
Actually my screen looks different, now it shows the build platform of a Replicator 2 (my printer) It did not do that before, and I'm pretty sure that the software was fully updated !!
Thanks for your input.
