On the Sims 3 community website, it seems that I am unable to change my profile avatar to any of my uploaded Sims as they do not appear on the list. I am currently signed in and have about 53 creations uploaded to the exchange that I should be able to use as my avatar but it's just not available for some reason. I've also been trying to switch avatars since December, I believe.

@AlienOrigin10 If I move my mouse over the avatar it says change picture at the top of the avatar. Then I get box where I can upload a new picture (user created).

I think that's what I did. The picture I uploaded is what comes up when I select "Uploaded Sims". Usually there are a bunch of Sims there to select from but now it's just blank. Just checked again today and it still remains blank. If that isn't what you mean, then I can't access the box you're talking about it for some reason.
