Since 1.011 i've never "deleted" anything. I let hoster install wizard uninstall the old versions for me so I don't have to go online to reactivate it. I'm using an Athlon 2500. Crashed a couple times one night back in Dec or Jan (heat related I think) but no problems since then - 7 nights a week (no days off since Christmas
), 5 hours a night, 1-3 singer discs per night.
