Cheers for replying cakemeat,
Well finally got the update done at stupid oclock in the morning!! I didnt change any settings. Just kept rebooting the router and re-trying.
After 3 POL-0205 errors in a row it just worked!! Im pleased but cant really throw any light on what the trouble was.
So if anyone else gets this problem my advice is make sure your router ports are set correctly or better still use uPNP and just keep trying!
Cheers.
