After updating my iPhone4s to the lastest update my photostream stopped updated onto my comuter. From my phone it looks like pictures have been moved into the photostream folder... but they are not showing up on my computer. Help!

I have signed out then back into the cloud. I have comfirmed location of the photostream folder. I have have even restored settings on my phone. any ideas on what I can do to get it working again? or do I have to accept defect, and manually save my photos?
