In need of help...R4 Wood

Okay I am new to roms and what not and I'm infact a noob when it comes to R4s. Anyway, I downloaded Wood 1.12 hoping it would help with trying to play PKMN Black. First off all I get is "errcode=-5" when I try to start the rom and then, to prove how much of a noob I am, I haven't got a clue how Wood works. My R4 card says:R4
Upgrade
Revolution for DS
(NDSL/NDS)
www .r4i-sdhc .comI downloaded the "Wood R4 For Clones" and I didn't understand why the file was an nds file.Can anyone help me out with these problems? I would be extremely grateful.EDIT: OH, if there's anything else you need to know just ask. :)

a bump can't really hurt this topic, it ain't to low ;)you got a clone dude, Wood R4 won't work with it, you're better off buying a new flashcart :P (anything without the name R4, preferably SCDS2)
