I just loaded the latest MUSE version, and tried to publish the test site. BC wouldn't let me sign in through MU , I timed out. Then I closed MU and reopened an hour later thinking it might need to be refreshed due to version update. I opened BC directly and made sure I was connected there and in good shape there -- I am. Again though, same problem when I want to upload my MU site. I need a test site up asap to show client for comments.
Try the solution here Trying to publish to my BC from Muse and it times out. should help.
