xml rpc problem while moblogging..

i’m using Azure ( http://web.vee.net/projects/azure/index.html ) a free blog client for pdas (in my case, a nokia 6600 with SymbianOS) to try to post to my wordpress..
everything is alright while writing down my post (shows categories, post fields, checkbox for comments, pingbacks and everything i normally see using my pc for posting), but when i try to submit i get this kind of error:
“a communication error occured talking to the server: unespected: ParseEvent type=256 terxt=” @-1:-1″
could this be a problem from Azure or this could be related to wordpress? azure is actually working with all the blogging platforms, could wordpress be incompatible with it?
