Found a solution for my issue over at the live mesh forums...
I checked under tools/connections in IE and discovered that my connection method was WAP, which was incorrect. I changed it to "entire internet" or similar and my IE started working... and so did Live Mesh Mobile.
By using those steps I was able to get the app to work.
Vazguard, this may help.
