SmartFTP won't open anymore?

Over this past weekend, I suddenly am suffering from my SmartFTP Client no longer opening, and I'm not sure if it has anything to do with a hacking attempt on my website. Using Windows 8.1, anytime I try to turn the program on, it shows the working icon, then a beep and stops.

I've also attempted to go to the SmartFTP site and download the latest version, but I cannot run the .exe to even do a clean install.
What would you suggest I do?
