As the website displayed on the card is no more , I would say you have two routes, 1. buy a new card or 2. Try every r4 clone firmware you can find online and hope to god one works.
Thanks Pika_power, I just purchased what I though was an R4i-sdhc but was really a R4i-DSHC. Now I'm just using the TTDS 1.17a12sp5 firmware and that's loads better .
