Update Cross 3.3RC1 to RC3

Hi Guys,
I am just about to update Cross 3.3RC1 to Cross 3.3RC3 to see what it's like.
Can I just run the installer over the top of 3.3RC1 without loosing anything or are there any update procedures I need to follow, just don't want to loose any of my collection in the process.
Cheers John
