Ideas Save Error

K I played Pokemon diamond and saved my game later i came back to play it and i get this error when i try to click on my save."A communication error has occurred.If you were in the union room, you
will be returned there.
In all other cases, you will be
returned to wherever you last
saved.
Please press the A Button."How do I fix this problem???

Have you tried pressing the A button? What happens?

I once had that problem but i solved it here:1.Download wifi plugin from Ideas website (I forgot it lol,so use Google)
2.Its a .rar file so you need WinRAR install it (ignore if already owned)
3.So extract it to your Ideas folder at the plugin/s folder.
4.Try it again
