Was using TexStudio with I think MixTex or something as the source of all the LaTeX coding stuff.. anyway I was using it fine, and had a working document that would produce a working pdf, until suddenly, without changing the input whatsoever or entering any other programs, it stops working and spits out the error message:
pdflatexdef.exe: The script interpreter could not be found.
pdflatexdef.exe: Data: scriptInterpreter="perl.exe"
I'm on Windows 10 so I should probably blame that; should I just download MixTex again or should I do something else simpler or does someone know why what just happened just happened?

As @Ulrike Fischer already mentioned, have a look at Options - Configure TeXstudio and point to the path where pdflatex.exe resides on your computer. This is C:\Program Files (x86)\MiKTeX 2.9\miktex\bin in my case.
