If you "lost" the blinkie at the bottom of your signature recently - well that's my fault. We are getting ready for a big server move and I've been doing a lot of cleaning up. I had to move all the blinkies into a new folder and give many of them a new name, which ended up breaking the links in your signatures.
Here is the list of all of the new urls for all your favorite blinkies. You can go into your profile and edit the signature and just replace the old URL address with the new one. I'll also ask April to look out for anyone needing help with this.
