HELP with Moving pictures from my Verizon LG Dare to my Micro SD card!?

Im trying to transfer my pictures from my Verizon LG Dare to my micro SD card. It will move 2 or 3 pics, then will stop and it will say "cannot rename". So I talked with Verizon and they told me I might have a bad micro sd card and to buy a different one and that should fix the problem. I bought a 34.00 Sony Micro SD card and it does the same exact crap!! I do have a lot of pics on this phone... I am a new mom to a beautiful baby girl, so lots of newborn baby pics that I do NOT want to lose.Can anyone tell me what is going on or help me with this situation.
