SCT SF3 wont load custom tunes? Failed to write data error?

[bigugly78cj5]

Was wondering if anyone has experienced this issue before?

Im trying to load a custom tune(looney) from vivian at quicktricks and i keep getting an error on the SCT device updater when i try to transfer the tune...

Heres the error in full

system.io.ioexception:failed to write data
at SCT.IO.Livewiredriver.writebulk(INT32pipe, Byte [] data)
at SCT.IO.Livewiredriver.Sendcommand(USBcommand cmd, byte [] data)
at SCT.IO.Livewiredriver. send file(string file, byte[] data)

The SCT device is older it seems and used, but is unlocked and had 4 unlocks left? i updated the firmware already....dont know what else to try...

anyone have any ideas? its driving me crazy, was going to be my first try at a custom tune...........
