Finally, I got the program going again, through XP Pro. It was going nowhere for four days on 7, it made it to 120/125, then the system crashed & restarted. After over three weeks of non-stop running, it came right back on. But I tried a different approach, I went back to XP, repaired the program, and have completed one and a half work units since. Hopefully by sometime in the morning, this one will complete. Funny thing, the lower the number, right now it's at 97/250, it takes longer than the 2500 one that I completed yesterday. But it does seem to be moving forward again, that's the main thing. Hopefully, it will run another three weeks before it crashes again, and get some work done.
