Hey guys.
First off, I'm sorry if this has been asked before.

I downloaded a house that has an elevator. Suddenly the elevator stopped working. It's now invisible and the sims don't have any type of interaction with it.
How can I fix it?

Thanks in advance for all your help!

I don't know why but everytime I send my sims to go to the mailbox, they just won't go! They get there but then nothing happened.
I already got a warning saying that I don't pay my bills in over a year. It said that there was going to be measures. What is going to happen?

I have all the expansions installed.

Please help!
