R4i card not getting recognised in DSi

[flash70]

Hi All I have a problem with my daughters DSi R4i Revolution Card.
It did work fine then it stopped working as if the card was taken out the dsi.
I upgraded the firmware on the dsi after it stopped working and its showing version ver 1.4.3E which was maybe a bad idea.
Here is the web link on the front of the card R4,R4dsixl3d the beta r4 card
I formatted the card and downloading the software from the link but the dsi will not recognise the card at all.
Any help- would be much appreciated. Thanks
The card looks like this

Hi I have looked at the site you downloaded from seems you downloaded patch not firmware it's 2.5 in english further down page. There are people on this site with more knowledge of dsi so have a look through threads. Go to forums then ds. Also make sure when you download you extract files. Good luck.
