Yes, I also experienced the same thing. I have a Blackberry 8310 and also an older version Blackberry 8707 and the application does not work on either of these - DESPITE the 8310 being 'supported'.
Accepting, that sometimes these applications need some 'bedding' in and despite continuing with some 'fruitless/unresolved' technical support (for about 4 months); I eventually received an email saying, 'we have no idea why it doesn't work!' (sic)
I'll see if I can dig out the email I got from 'Mr Angry - don't you know I fly a 777' as it's also hilariously dismissive.
I didn't bother mailing after a while. Over time, I have just learnt that he's a ****!
