I have a new ( to me ) computer with two hard drives. One hard drive has win XP SP2. and the other hard drive has Win 7. I installed mach3 v 040 on both hard drives. I use only one hard drive at a time (  disconnecting the other hard drive so at no time are both visible at the same time ) On each drive I set up a profile identical to the one I had on my  old computer ( it died ) . When I start mach in either windows,  I can't get past the reset, says e stop is set. It will reset in off line mode. Nothing is plugged into the computer except what needs to be there.  This profile worked with my last computer with XP. No other programs are running in the background, both operating systems are new installs and no other programs are on either drive.

Anyone have any suggestions?
