Lego Batman 2 (U) problem please help

i was so glad to see a (u) version of lego batman too, however when loading up on my r4i sdhc it gave me an error code
saying disk errcode=-82.
how can i fix this? i want it to work, as i am on a long trip away this weekend.

Download RGF's Latest YSMenu.
And then use Jhon591's latest dats.But there is no AP in this game, so it is probably just an outdated firmware.

thanks have you got a link for this?
