Blackberry and Capitec Bank Question

Attention Mods, please move if its posted in the wrong section, thanks.

Hi Guys

Got myself the Blackberry Curve 9360, went to Capitec this morning for their Banking App
Back home I logged on to their website a SMS was sent to my BB Curve 9360 I clicked on the link and the App was downloaded no problems at all.
Now here is the problem....I need to open the app to complete the internet setup every time I try to open the App I receive an error message "failed to establish a connection".
My internet is working fine why would it not allow the connection?

I'm on prepaid and don't have BIS on the phone.

Anyone else had this problem?

Your assistance would be appreciated.

Thanks in advance.
