Try to not just put your topic title as 'help please'. 
On topic, you can try this:
try the following:    
Start > run > type: regsvr32 softpub.dll <enter>
                            Start > run > type:  regsvr32 initpki.dll <enter>
                            Start > run > type: regsvr32 mssip32.dll <enter>
Tell me if this works at all. 
Also, try a different version of MSN Messenger. And do you have any plugins at all?
