Usb network transfer of files

hi there, i have downloaded and installed the wd link program from wd, but when i go to transfer a file to the usb connected to my wd live media player it comes back saying there is a problem accessing \*****\lexar  make sure you are connected to tthe network.  i have disabled my firewalls and anti virus programs and cannot determine the problem, please help.

ok update…it seems to copy over small files but not large one. i copied over a 75mb no problems but when copying over or 211mb file but when i try a 600mb file thats when i get the problem.

cheers
