I purchased my version 4.0 some years ago but have only just got around to trying to use it. I downloaded the disk and all seemed to go well and installed, i didn't try to use it though but i did notice that i didn't need to enter the serial number at that point. I went to use it today but can't find the disc cover anywhere, i think it has permanently gone now.
I hadn't logged in to this online site to register it at this point so is there a way to get a new number or find the old one somehow?
