Sounded a bit stupid of me I know, I meant the last 110 copies were 80 bad to 30 good.
It seems I now have to reset the computer, shut down any non-essential Programs running in the background then place Norton in silent mode. This lowers ram usage down to around 15%. Have wasted only 1 in the last 14 copies. Waiting for the next batch of disks to come in from my wholesaler.
Great forum by the way, people discuss things, a real pleasure talking, if only to vent my frustration!
