computer

Hey, it worked great--I replicated several sets of messages without a
problem. Then, on Sunday, I did something and now can't get the computer to
load up windows. It stalls out on the "Property of ET&S" screen right after
I turn it on. Please make it happy again and ship it back up. (I don't know
if this would cause such a problem, but I may have shut off the computer off
on saturday before I got the message saying "it is now safe to shut off your
computer." ) Thanks. DF
