can't open bookworm from R4 card

Hi, I've done a search on this problem which seems to be a common one and the only fix I found I couldn't follow the instructions :-[Please be nice to me I'm a complete newbie!I have an R4 SDHC Revolution card which I have put the latest firmware from www.r4sdhc.com which was R4 SDHC Kernel upgrades to v1.34. I have also recently put YSmenu on my R4 to fix some other problems which I followed the instructions on this link http://forum.romulation.net/index.php?topic=28719.0The card is playing all the other games I've downloaded beautifully but when I try and play Bookworm it opens a save file for it then when it loads the game comes up with the message:
load rom errcode=-4 Please reset systemIs there a fix for this? And if so can you please give me the instructions for dummies :DThanks in advance!

You could try using the Wood R4 firmware? http://gbatemp.net/index.php?showtopic=221023

forgive me,but you can invest in an ACEKARD 2i and really never have these problems again.good luck

Or, you could use wood R4 which has almost the same compatibility as the Acekard for free...
