Fatal Error opening both MonoDevelop and Xamirin

So last night I had a load of fun with Unity, and by fun I mean spending 3 hours uninstalling and reinstalling unity and monodevelop to try and get it to open. Every time I double click a C# script, the loading circle appears, spins a few times, and dissapears. Monodevelop doesn't even try to open. I tried opening MonoDevelop through the .exe in the .bin folder, and it won't open that way either. There are no monodevelop background processes running that might interfere. I have all the necessary microsoft packages, like the "build 2013" or whatever it is called. I have tried putting some very strange .dll file in the .bin folder that looked 100% like a virus. Didn't help.

So today I downloaded Xamirin studio, and I think I've narrowed down the issue. Whilst it won't open, in the appData folder for Xamirin 6.0 I have found a FATAL ERROR line in the log (about 4/5 of the way down). It crashes/closes when the monodevelop packages are loaded in. I will add the entire log for the program opening if that will help. I think there is something wrong with either my system or with the monodevelop packages. Any help is appreciated, thanks.
