I need some help with downloading GPO4 please.
The download site tells me to register first. When I do that, I am asked for my serial number. In response, I type in the serial number of my existing GPO (that's the only serial number I have so far).
In response I get one of two messages, either I am told that my serial number is incorrect (it isn't) or "A serial looks like 12345-12345-12345-12345-12345 and containes no spaces nor letters!", which is exactly the format I have typed it in in.
So, brick wall.
