I replaced my old system with cheap. Its a dual core celeron with one gig of ram and a power supply that sounds like a 767 taking off! For $250 I figure I can't go too far wrong and its not too hard to improve on the performance of my 386.
The fix turned out to be both simple and stupid. There is a script error in the install (I think). The registration window was waiting for a carriage return. I tried mouse clicks and gave up, trying to use the norton repair tool to fix things. Looks like the Norton tool was breaking the ISP version.
