Do you use a proxy server?

Do you have the latest version of WLM ?

Also, have you tried any of the usual fixes for this?

1. Verify your date/time is correct.
2. Verify your IE security settings (use SSL2.0 and SSL3.0).
3. Reboot your computer.

no i dont use proxy server

yes i have the latest version available from microsoft

already done many times

Since you've done a lot of the suggestions already, here's some more stuff to try on this error (from a search):


Re-register the files:
First open a run window by clicking start, then run. Now, type the following command and press enter:

regsvr32 softpub.dll Wintrust.dll Initpki.dll Rsaenh.dll Mssip32.dll Cryptdlg.dll

If you use Windows XP you should open another run window after running the previous commands then type the following command:
regsvr32 Dssenh.dll Gpkcsp.dll Slbcsp.dll Sccbase.dll
