r4i gold

i have a r4i gold, i am new at this, so be patient,, bought this card from Craigslist, it had some games on there that my daughter didnt like, i am trying to download the games she wants ..
i formated the micro sd... i downloaded what i think is the latest from r4i gold web site..
i have a dsi 1.4u version
i have a mac, but also tried on my pc running windows 7
i have got games from coolrom.com..unzipped, they show to be on the card reader?
when i put cartridge in , the dsi show no disk inserted,,,????what am i doing wrong, i think its the original download to micro sd.. stuck???????

did the card work before trying to change the games?

yes, i bought the card with 30 games on it, but none were the ones i asked for,, my 10 year old is wearing me out!!!!

and did you update the ndsi while having the cart?

no, there are games on the sd disk , but ndsi says no game in slot

try blowing inside the ds, it could be dirty and affecting the conntact with your ds, if that doesnt work. backup everything, and format your card

my dsi says its version 1.4u the r4i says v ersion 1.4....i tried it in another ds, not a dsi and it said no game in slot also

it could be contact issues...
