R4i-sdhc wifi 1.4.1 help desperately needed!!!!!

Hi all, new on ere and desperate for some help.
appologies if this as been posted before.
I recently got myself a R4i-sdhc wifi 1.4.1 for my niece's dsi along with a 2gig sd card.
i've downloaded the latest firmware from the r4i website but am havin no joy.
the dsi recognises the card on the main menu but when i click on the icon i just get a red menu box on the top screen.any help or suggestions will be most appreciated

Have you extracted the firmware using winRAR before you put it on th sd card?
Can you try putting the firmware on a diffrent sd card, it may be that your sd card is no good.. you can also try formating the sd card?

hi goodle, thanks for reply.
yeah tried all the above. gave up in the end and took the card back for a refund.
thankyou anyway.
