game dumping on 4.2

[my_rig_is_dust]

Hi, I used the wii wifi dumper to dump my games with homebrew. I used a Ios starting with the number 2. all was fine on 3.1 untill I updated to 4.2. now the cIOS wont install (it returns an error of -1). I really want to dump a new game I got, and dont want to buy one of those LG drives. should I downgrade or is there another tool compatible with 4.2?
Thanks

Check if superdump works

Ok, I'll try it now, after I FINALLY found my 8 gb sd card

Ive tried it, and every time I load the app I just get a black screen.
Help?
