hello, i have a vista problem loading dat files and running rebuilds. it was working fine on version 3109 and all the sudden it slowed to a crawl. i have moved to another drive and checked permissions, loaded 3109c and still the same problem. if i actually wait it crashes during rebuild but take and hour to get there. i have 4.1 dual core processors and 4gb ram so shouldn't be slow because of that. any suggestions? thank you.
