I installed windows 7 service pack 1 yesterday and now I can't upload to any of the sites.  The upload stalls and I get errors with FTP and with using the online methods.  Anyone else having this problem?

The problem was that my PCtools firewall didn't work properly after installing service pack 1.  I changed the firewall and it's OK now.  Just thought I would mention it here in case someone else has a similar problem.

Seems you are not the only one plagued by update problems:

Here is a ZDNet article (and perhaps the fix):
