Same issue for me. My last image on WU site was at 5:10am on Sept 12th. When I do an FTP test, it says "fail".
I sent an email to Kari at WU, since she was very helpful in helping me get my cam on line 6 weeks ago. No reply yet, although I would imagine she is being flooded with emails right now.
WU should have done the right thing and communicated the issue to all of us, since by now it's obvious that it is an issue.
