I updated from 5.5 to 6.0 to see if that would work.... Nothing.
Google and sometimes different pages are blocked.
Did you try suggestions from the last link I sent?
Here is one of the suggestions from that link
http://support.microsoft.com/default.aspx?scid=kb;[LN];246725
Here is another suggestion from that link
Register the following system files
Click Start > Run
Type “regsvr32 softpub.dll” (w/o quotes)
Press OK
Repeat the above steps for the following:
regsvr32 wintrust.dll
regsvr32 initpki.dll
regsvr32 dssenh.dll
regsvr32 rsaenh.dll
regsvr32 gpkcsp.dll
regsvr32 sccbase.dll
regsvr32 slbcsp.dll
regsvr32 cryptdlg.dll
Page two of that earlier link had a couple different suggestions for router settings (scroll down read replies)
