Thanks. I managed to get X11 as handrawn suggested by logging into my account and downloading it from there. I had to type in the serial number manually though as copying and pasting didn't work.

I haven't noticed a great difference in the last few versions. Thankfully X11 has the shadows and highlights brightness in the photo enhancer. I can't think of anything else I need that this version doesn't have. I've never really used the designs gallery or online content.
