Heroes of mana PROBLEM!

i just download heroes of mana for my R4 SDHC and have a black screen when i try to load it ... can som1 help me?...i would really appreciate it//

This problem should be in technical support.ANYWAY, is it only black or does it say something? (eg. please turn off the power and re-insert the disc) coz wen i played it, it was fine.
