I've got a very strange problem. Just installed a clean win7, and tried to install windows live messenger (latest version). Downloaded it from the live.com website. After installing wlm, I wasn't able to connect, and I'm not able to open live.com and msn.com (incl. all the sub-domains). Even after removing wlm, I'm not able to open these pages I receive an error code: 80048820 I cannot ping or trace live.com, route table looks ok..... what can it be ?
