I might sound a little bit like a nood, but I'm having troubles getting the Backup loader up and running. Please help!!!

On my SD card I have got IOS36-64-v1042.wad, a Wad folder with the region files for Wad manager 1.3, cIOS36 Rev 7, and the DVDX installer. First I loaded the Rev 7 in the homebrew channel and accepted, and installed. Now I am supposed to install DVDX , Advance install, cIOS249. But 249 isn't there, and the closest thing to it is 254! What do i do?

Oh, and if it helps, my system menu is 3.4.
