So after 20 days of no crashes, I've had 2 in the last couple of days. Once on the 24th and one just now on the 26th. I ran the program again and have attached the latest zip files. The only thing that I have changed is I upgraded to Windows 8.1 on the 24th, I'm not sure if that has something to do with it.
I'll go back and have a look at what to try next to try and solve this issue.
