Vodafone 3g data card!!!!

Hi,

I've got a vodafone 3g data card with a pay as you go sim card.

I've still not got it working yet, despite a whole month of going back and forth to vodafone!!

It just won't connect at all.

Just wondered if anyone has experienced problems with vodafone and thier data card?

Have you had any luck?
My USB modem was working perfectly, then all of the sudden the Vodofone mobile connect software reported an error: Application not responding.
I have tried re-installing the software, but no luck!

I have to surf on my PC laptop that really sux!

Have you got any pearls of wisdom that could get me 'back to Mac'
