You could also download the Smith Micro downloader. If you still have your serial number (which if you can boot up the old pc lists on the open screen) you should be able to download a fresh copy of PP2014 and it's patches. And as far as rar files 7zip (a free program) works on rar and zip formats. I highly recommend the program.

The dust settled, thinking "what a fine home, at least for now" not realizing that doom would soon be coming in the form of a vacuum cleaner.
