guys i really need help!

okay when i lost my curve 8330 i received a new 8330m curve from the insurance and this phone was capable of get the actual reg pics and motion pics (.gif) good....until recently....i still get my reg pics but now my motion pics don't move on my 8330m....i need help on how to get this to work again...i talked to sprint and some girl told me that the motion pics expire but i get new ones and don't move as well...if i can get help on this it would be awesome! thanks in advanced?

sorry if there is a topic on this but i searched and searched and couldn't find anything!
