From: Morris Neuman on 7 Jan 2009 10:20 Yes that sound good. Just two questions 1. Where on my system do I see the Upgrade Wizard log? 2. I tried to use Outlook express Mail reader to access this forum and get the following error: ------------- 502 cv.net: Access denied to your node - news(a)cv.net Configuration: Account: MSDN Server: news.optonline.net Protocol: NNTP Port: 119 Secure(SSL): 0 Error Number: 502 Code: 800ccca0 --------- I can access other forums like microsoft.public.dotnet.framework.aspnet which also give that error but then go on to list all the postings. But this vc.language forum does not display any postings.

However, this is not necessarily a good idea. It is hard to be sure where they are going to land, and it could be dangerous sitting under them as they fly overhead. -- RFC 1925
