Hello All, Really hope someone can help me out here I have the AAO running Linpus lite and am very happy with it, all updates done and works pretty much like a dream so far. The one problem I have and its not everytime but when I log into messenger using the messenger service using my windows live account it more often than not trys to log in then gives me the following error message "Messenger Invalid Certificate Chain. The certificate chain present for Contacts.msn.com is not Valid" I then click on OK and it then trys to still log in but doesnt. If I then stop it trying to log in and goto accounts settings and edit my windows live account to use a "Windows Messenger Compatible Service" by ticking that box it then will log me in but I cant see my previous conversations or history, or use video chat etc Whereas when it does accept my login without having to tick the use the "Windows Messenger Compatible Service" box I can use all of these services with no problem. I would say I am having this proble 8 out of 10 times when i log in. It appears it sometimes just wont properley log me into Windows Live and Im having to use some sort of compatible service instead that doesnt have all the bells and whistles, if being unable to log in was due to windows changing something then i would of thought it would fail everytime but it doesnt just intermittently ?? If anyone has any ideas I would be really grateful...BTW Congratulations on a great forum..loads of good info on here.. Adey
