hi
Is there a place where I'm supposed to put that new number and how do I get to it?
Yes there is such a place
When you start the program there is a memory test, in that memory test window there is a button called Registration(or something like that, I don't know the exact name, because I use the Bulgarian language pack), when you press this button a window will appear and in that window you van enter the new registration key.
Or there is and another way. Right click on the "
a" icon in the system tray and from the pop up menu choose
About avast! in the appeared window there is a button called
Registration key , push this button and enter the new registration key
