New beginning

Well guys, I'm asking for some suggestions. My computer was stolen, and recovered. They restored to original. I have all of my files backed up. All of my files were created with Sketchup7. I'd like to install the latest SU, but will my old files work with the new SU? It has been 4-5 yrs since I installed SU, so some hints and tips would be greatly appreciated. I also have used the Sketchucam with great success. I had 1.4 working great in SU7.

Thanks
Jeff
