Thanks. I tried disconnecting the network cable, turning off the firewall, turning off all security measures, deleting all registry entries and entire directory in 'Program Files'. Still no joy.
Looking through my change notes, I did a monster Windows update just after the last ripping session; probably five or six years' worth of XP updates since the machine had a clean XP SP3 install and update. I suspect something has been broken by one of these updates. One reason why I've stayed offline for so long; the computer worked, and didn't need fixing. All these marvellous updates seem to do is break things...
So I uninstalled 0.99pb5 and tried a later version I had kicking around, 1.0beta3, which I tried but didn't get on with; I have a long bug list for it...
But this did boot, and allowed me to configure it.
Tried uninstalling & re-installing 0.99pb5, but it still hangs.
So it looks like it's a problem with one of a huge raft on Windows updates, and the later EAC fixed it. So I'll have to go and get the latest EAC and see if it's improved over 1.0beta3...
