Alright, I restored my system to an earlier time and got most everything to install. I was test compiling the examples that came with evc, but it said some files were missing and couldn't be loaded into the workspace. I'm currently (as in this very moment) uninstalling and reinstalling evc, platman, evc sp4, and the pocketfrog library (in that order).
Is there maybe an alternative (free) IDE I can work with? Or at least a compiler that I can use with dev-c++ along with the instructions on how to set it up?
