DS Fire Link Card- Save Data cannot not be written/corrupted

Hello,I brought a DS Fire Link Card about 8-9 months ago and was quite happily and easily putting games onto the card and being able to play them. Although, i then recently tried to add the following games:Air Traffiic Chaos:
This worked, but i was unable to save.Sim City Creator:
This would not load, it instead gave me a screen saying that the save could not be loaded. Rendering it unplayable.Sid Meiers Civilization:
The was playable, but again like "ATC" it wouldn't save.The Ledgend Of Zelda: Phantom Hour Glass:
This played fine even after telling that the save file was corrupted and would need to be reloaded. It even saved, but was deleted on the next start up.Please,
if anybody knows why this is happening, seeminly to any new game i add, and how to fix it. Please tell me how! I will be very grateful!Thank You in advance,Parragon
