Thanks sooooo much! In the Sims2 Clean installer I cleared out a bunch of "crap" and got rid of a couple of hacks that I was unsure of. My sims now greet their guests and the hot tub and pool issues seem to work as well. Thanks for everyone's help. I really appreciate it!!!!

I downlloaded Sims2pack. That is awesome! One question, some of the files come up as under type as empty package. What does that mean? And a few give no description at all, could those be the hacks??
Thanks sooooooo much!!!

quick question before I get into my game again. Is there a way I can go into my downloads folder and find files that are hacks. Are they named a particular way? I've looked down through them and can't always tell what is a hack or just clothing, object, etc., download. Thanks for everyone's help

Oh, I don't know of any hacks that I've downloaded dealing with visitors. Unless something has popped up in a download that I don't know about.

Sorry, I should have given more information. I have all the expansion packs (indluding family fun, glamour stuff etc.) except for Pets. I went into my game and tested a few things out. My adult sims won't greet anyone on any lot. They can throw a party and greet people but during many of the interactions they will suddenly stop and pop away. Both my teens and adults will get in a hot tub or pool and ask someone to join then will pop out and there isn't an option to get them back in. This is the same when they are eating dinner.

I'm not sure what's happened but my sims suddenly won't greet anyone they've invited over. They ring the doorbell but I don't get the option to greet them. Whatever my sim is doing at the time of the ring, they move and stand somewhere else. I try to click on the person I'm greeting and It says that no actions are available.
HELP!
