Hi,
It sounds like you've got some sort of problem with the VMB application, or something is conflicting with it. Given that you've tried a couple of different version and an uninstall, clean up and reinstall I would suspect the latter.
Both the VMB applciation and the native windows connection manager both use the Mobile Broadband network adapter (in the device mnager) to connect. You know this network adapter is alright as the native connection manager works.
You could try using the applciation conflict manager to reolve the application conflict (if it is this that's causing you greif). If you open VMB, switch to advanced mode, click the round red icon in the top left hand corner, then click on options, then applcaition conflicts, tick manage application conflicts and select auto resolve.
Alternatively you could google everything in your task manager processes and services and see if there's anything in there that relates to network, mobile data or connection management and then kill these relevant process/services. A bit brutal, but it might give you a clue or fix things.... maybe.
There isn't a more recent version of VMB 10.2.401... it only came out in April.
Vodafone do offer support to their customers, and usually you get transferred through to the relevant people after placing a call into customer services. Given the nature of the problem you have it's highly likely that you're going to need full admin rights on the computer to resolve it. It might be a plan to give your laptop and dongle to your IT guys and get them to call Vodafone on your behalf. It might be worth your while being ther when they do this as they may well need to check the accoutn holder is present or something.
Good luck, and feel free to post here if you need to.
