Ok. Heres where I have got so far..........not very far.
However, I have found the problem. The drivers are not installing onto the X5. The .exe drivers setup file which runs on my laptop, with Active Sync running and PPC connected, runs through the complete set-up, including where the add/remove active sync pop-up appears. However, it doesn't ask me if I want to use the default directory, nor does the drivers appear in the add/remove window list. This just leaves me to select OK or cancel on the Active Sync Add/Remove and then the setup program says install finished.
End result, no drivers unstalled on the Axim.
