I had bought Nero 6 Ultra Edition when Nero just came out with Nero Ultra 6.... like in September 2003.
Now I was trying to update it with Nero 6.3, but it won't take the 6.0.x registration code ?
Well it should accept it with no problem. I do recall there was some problem with early serial numbers as there was a news report from Ahead about it, but it has been taken offline now.
I suggest contacting Nero support.
Really ? so there was aproblem... well, I never got any email from Ahead...
I'll contact them. Thanks
