Avast for PDA: "Invalid Licence Key" Mesage

Avast 4 for PDA doesn’t accept my licence key,
returning a message that the key I have (very carefully) entered (several times) is invalid.

I am using an iPAQ rw 6828
running Windows mobile 5.1
and have installed Avast 4 for PDA
(engine version 4.1.19)

Both update and scan work fine,
just the licence key isn’t accepted.

Thank you for any help.

I have one PAD, do Avast for PDA need another licence key?

I think avast requires one license per PDA. Maybe you could ask for a discount.

So if you haven’t got the latest version it might be best to download the new version, uninstall the old version and install the new and enter your key.
