I also have this problem. It's not worked since this time last week, absolutely fine before that and i've been a member since June. I emailed Weight Watchers Tech Support and they say that there is no problem with their website, told me to clear out my cookies (no instructions given for Firefox) and try again... still no luck. I've emailed them again.

I am having trouble connecting to their IPod App too, not just at home but at work aswell.

Paying for this service and not getting it, making it very difficult to track and make recipes!

So I had the same issue as most folks on this posting, able to connect to weightwatchers at work or on my I-phone but not on my home computer. I've been dealing with this issue for a year now ever since I upgraded my wireless router, but came across something that finally clicked for me. My issue had nothing to do with the computers but more the fact that I was using a wireless router. How I fixed the issue was logging into my router 192.168.1.1 and changing the MAC address from using the default MAC address to using the computers MAC address. This was a setting with-in the router itself. I saved the change and rebooted the router and computer. I have a NETGEAR router so I'm not sure how everyone else’s set-up is, but it appears to have solved the problem. Before this I could rarely get onto the weightwatchers web-site, now the issue has been resolved. Clearing the cache or cookies have nothing to do with the issue, it's all with-in the router itself, especially if you can get to every other side on the internet. My set-up is as follows, Cable -> Modem -> wireless router -> computer. Hope this helps.
