Hello all, I am new here but saw the problems that some were having and wanted to help and to ask questions.:D
I recently installed WinXP and then MSN6 and began having problems. MSN4.7, which installed with the OS, works fine, but ver.6 would not allow a sign in. I got the error that stated it was unable to connect to the SOCKS proxy server. Since MSN4.7 worked I decided to do some comparisons.
In the setup for MSN6, I found that the section under TOOLS/OPTIONS/CONNECTION has a tick box for “I use a proxy server” and the box was checked. Also, the selcetion for ‘Type’ was set to ‘SOCKS Version 4’.
In the setup for MSN4.7, this box was NOT checked.
So, in MSN6 I UN-CHECKED the box and tried to sign in…and it works fine!
