Well, good news - I reinstalled Pets, removed the cd, reinserted the Seasons cd and it all worked fine. Pretty cool so far, despite my "oh shit!" reaction at first. But now, family obligations require that I go out to dinner (crappy timing, I know) so I'll have to check my old 'hoods later - I only played the new 'hood for the few minutes I had available. Don't ya just hate it when RL gets in the way of fun?
