Suddenly my editing options have gone from about 12 to 3

Nero is a bad software company in my opinion. I've used them since they came out. For photos I recommend Microsoft digital suite. You can do so much more with them and never have to upgrade the product. Nero gives you software with new computers and computer products such as lightscribe dvd burners. They are notorious for voiding serial keys validation after upgrading or downloading new updates. The software you thought you owned was just borrowed. They will claim you have to have a current key for the easy price of just "whatever". There software can be nasty to remove also.
