Since I'm not a windows user I can only surmise that your problem is due to the SP2 update. It has caused many people problems. There's been a number of solutions suggested, BUT one may fix your problem but not all. Each person's comp is a little different. SP2 reduces the connections (or something like that) that can connect to your computer. There's a patch & there's also other solutions. Dare I suggest it, but do a search of the forum using the term SP2. Use the search button at top-right of page inbetween faq & home buttons.
