XML-RPC Response Error

I’m using Mars Edit to post to my WordPress 1.5.1.3 weblog and I keep getting: “Cana€?t post for Outdoor-Adventurer because The data was not a complete XML-RPC response.: XML-RPC Response Parsing Failed”.

Funny thing is, before I upgraded, it used to work fine. I’m having the same issue on two seperate blogs hosted in two different places. Any thoughts or insight would be helpful.

I am able to post through the web interface fine. It is only when using a remote client I have issues.

Thanks in advance.
