Forum:I can't use my modded character on borderlands

I modded my character for borderlands (Made some fun weapons, put him up to level 61, and gave him the skill points for level 61), I watched videos so that the guns would work and downloaded the new Willowtree (Beta10r13). When I was done I used the hash block calculator (It said everything was true) and then I injected it back into the correct folder (with usb xplorer) on my usb and then put the usb in my xbox 360. Put the new savegame in my hardrive and started up borderlands but when I went to singleplayer it opened the window 'Loading Savegames' and then my console just froze. I know its this character causing the problem because I went into splitscreen and loaded that character specifically and my whole console froze completely. Anybody got ideas of what I should do? Btw I also tried using an older version of willowtree to mod a weapon but when it didn't work I downloaded the new one and started watching tutorials on Youtube.
