Help with Pokemon Black 2

Ok so I am running Wood R4 V1.52, and it seems I cannot get Pokemon Black 2 to work. Is there one available for Wood V1.52, or would I have to downgrade. Thank you in advance for your help.

I am currently getting a blue screen saying " The save data could not be accessed. Please turn the power off and reinsert the Game Card."

WoodR4 v.1.52 hasn't contain any fix for PKM BW2 (U), wait for v.1.53 to come out. Mean time, try using pre-patched rom. Delete existing save file, and don't activate too many cheats.

OK i tried using the unpatched version. I get the same screen, along with the exact same problem.
