I probably shouldn't post this here, but I was up against the same wall with MLXchange and getting it to work on my iPad.
I use Mac OSX, Linux and Windows at home, so I had to spend hours and hours figuring out how to make MLXchange work for me.
Then I got with some VERY smart folks and we have put together a virtualized solution that is a cloud based desktop.
It works super sweet for the iPad and for Mac. It is at RealMobilePros.com.
