having trouble ftp'ing files to my xbox

hey there. ive recently soft modded my xbox with the evolutionx dashboard and now wish to ftp some homebrew onto it, now heres the problem:

ive installed flashfxp, set my xbox's ip to dhcp (and Rebooted). and then i type the ip and password into flash fxp.

it connects fine showing the files on the xbox hd, and i even pinged my xbox's ip address with command prompt, to make sure it was properly connected. but when i try to send any files across i just get something like this:

502 pasv not implemented
Transfer failed

pleas could someone help me out

trust me i am xbox noob n1 but today i installed xbmc and i activated the fpt and by flashfxp i fpt video and music and pictures with no problem.
all i did was put xbox as pass and ass ussername and then i filled that in flash fxp and worked like a charm

i wont be around so dont reply OMG Sorry for dubbel post
