Travel Technology - Blackberry 8310 & amAze mapping

Has anyone been able to get amAze to work with a blackberry 8310? I receive the dreaded "Communication Error" every time I start amAze :( I would like to have some directions spoken to me without paying for it [something for nothing, isn't that what we all want?]

thanks,
E :confused:

I've got an 8800 and tried a previous version of Amaze and it was "buggy" to me, too. I've gotten Nav4All to work ok.
