Well, I'm disappointed.  I have updated all my drivers after trying to install Celebration (I have all the EPs and stuff packs).  I had a terrible time getting it to install.  Anyway, after I got Celebration installed, none of my ponds show the fish swimming any more.  These same ponds had fish before the install.  (My sims can still fish, however.)  I checked my graphics settings and they are all on high.  The game runs slowly with lots of lag on large lots at the best of times.
