Rhythm Heaven/Paradise

Hi,I have a DSTT card. I've put both Rhythm Paradise and Heaven on my card. When i want to open the game it keeps saying it's loading, but it's not doing anything..I need help! ;)

Is there firmware on the card?

yes there is.. Also the latest version. I just checked if there was a newer one but there isnt.
i have no problems with my other games..

Backup and reformat your MicroSD.
