VBA8 Import Save Help?

I have Pokemon FireRed ROM for VBA8 and wanted to import a save file to it but I'm having trouble getting it to work. The save file has the same name as my ROM and downloads from SkyDrive just fine but when I start up the game it says "The save file has been deleted" and it starts a new game. What am I doing wrong? Am I missing anything obvious? Thanks for your help.
