Try swapping in the 6.5.0 executable and see if things work. I'm betting that won't fix it though. Try looking in the /log directory and see what it says when you try to login (error.log file). I remember you mentioning something about bad host/ip. Try logging into the ioFTPD account via 127.0.0.1 and see if that works... Need a little more to go on because I'm blindly guessing here
