yu-gi-oh world championship 2011 over the nexus (eu)

i am using r4i gold with the latest wood firmware.
everything in the game works fine but the only thing not working is:
when i turn the game on, click on new game, and save the game.
next time i turn the game on again, it says i have the save file but there is not continue option.
i checked on my computer i have the file. but it just doesn't load.
