Re install your firmwire and everything will work again

Can you explain this a little better if you dont mind as im not great with computers etc??

I can do that it is not difficult and you'll learn it yourself
after a few times (Firmwires gets keeping updated so that
means every now and then you'll update your firmwire version)First download your firmwire: http://www.acekard.com/download.phpFor Acekard you'll scroll down the page until you'll see that the lastest
version is 4.11. download that one.(Note you also can use an alliterative firmwire named AKIO,
it is the best unofficial firmwire for Acekard and Acekard 2i
and it supports everything you can play the newest games without patching)If you want to use that download the lastest one here :
http://normmatt.com/forum/download/file.php?id=75To extract both downloads you'll need to have and use winrar
extract one of the downloads to the root of your SD card
In the AKIO case you'll extract a folder named AIO to the root of your SD.If you've done that put the flashcard in your ds with and start up and everything
should be work liking a charm.
