I recently found out that the Last Resort launcher has a bug in it when run under Windows 8. You should make the Last_Resort.exe run in Windows 7 compatibility mode (or even Windows XP Service Pack 3 mode) if you are having problems with it in Windows 8.
I was completely unaware that Windows 8 is very strict about saving the LastResort.ini file that stores the launcher's settings. Windows 8 redirects the file into a Virtual Store folder as a way to make the operating system more secure. The Last Resort launcher gets confused about the location of the file and crashes. Perhaps including a manifest file will fix this problem in future releases or perhaps saving the settings file to AppData. I will need to research this.
I understand why Microsoft does this but it doesn't mean I don't think it is a total pain in the ass.
