ok ok! This is the problem, For some reason this has occured in this latest version which was never had with any of the beta versions. Simply put someone hasnt put the WINHTTP.dll in with the installation and can be aquired online by googling that dll or from here :
http://www.dll-files.com/dllindex/dll-files.shtml?winhttp where i got it from. Then simply extract to the C:\windows\system folder and open messenger live!
Hope this helps all!
