Ouendan 2 Freeze Glitch

Well, I have been playing Ouendan 2 on my R4 for a while, when the game suddenly freezes during a song.The game freezes during the first cut scene of the song "Zoku" (the one with Meowzilla) on any difficulty (both Easy and Normal since those are the only two that I have..)
I have tried everything from getting new ROMs, to reformatting my microSD card. My other ROMs work fine so I don't know what is the problem with this one.Can anyone help? or give me an Action Replay code so that i can unlock everything and just skip this song?

first of all, is yur r4 a clone or real?if real, check out this siteits a compatiblity listhttp://wiki.scorpei.com/index.php/R4_compatibility_list
