KSP (64 bit) Never starts up and gives Black loading screen

[holmes323]

So I am trying to open KSP 1.1.3 in 64 bit however it never gets to the regular loading screen. I opened the launcher and hit launch it asked me to allow KSP_x64.exe to run, I clicked yes and it opens to this blank window with just the word loading:http://imgur.com/PvA4gGB

32 bit KSP works fine but I want to make use of 64 bit KSP any suggestions? BTW this is the first time  I have tried running 64 bit on the PC(it has a 64 bit CPU and OS)
