Default Trouble flashing custom recovery

i have the weaksauce temproot installed, unlocked, and s-off but i can't flash a custom recovery so i can install roms. i've tried philz and twrp and both times i get this error

target reported max download size of 1830711296 bytes
error: cannot load 'twrp.img': No error

this is the command im using "fastboot flash recovery XXXX.img"

I'm using win7 x64 if that matters. Any help you guys could give would be greatly appreciated.
