Yes, many people are reporting the problem with the Windows Live Communication Platform, hence the many links with solutions.
And, there are multiple reasons for the Live Mesh currently starting error.
So, for the Live Communications problem, I recommend that you submit a support case to Windows Live Messenger support:
Go to http://support.live.com/ and sign in with a LiveID
Click on the Windows Live Messenger choice.
If you are not presented with an email support form, but are instead redirected to help.live.com for that service/product, in the page that opens from http://help.live.com/ select any topic on the left hand side or search for a question in the search box.
The results of your search or the clicked topic appears in the right hand frame, along with a tiny link in the lower right hand corner – “Get more help.”
Click that tiny link and you will get to a page with a link “Contact support”
Click that link and you will be presented with the email support form to fill out. Provide as much detail as possible and you should get a response from support within 24 hours.
Help topics at http://help.live.com/
For the Live Mesh problem, if you have not already done so, please file a bug on Connect with your logs per the instructions here: http://social.microsoft.com/Forums/en-US/LiveMesh/thread/d52b350a-f3e0-41c6-8e78-d6378e566b9e
