I know it's human error. I never knew how to back up the registry, or even that I could. Again, not the most tech savvy.
I did a bit of looking to see if my PC had automatically archived my previous registry settings, but unfortunately, it seems like it only saved my settings at midnight, after the fact, and that's my only listed backup point.
Now I just want to know if anyone has the expertise to tell me what those registry changes added, what values have changed, and if I can manually put things back the way they were by going through individual items in the registry. I want to know exactly where to look, what the exact items are and what exactly I need to do.
I did get my screen size and taskbar back to normal by double-clicking "KONYAUS.EXE" in the game folder, which did boot up the game (although it did still seem to be unstable), and selecting the option to quit game. If I try to open the game again, the problem starts over, and I have to repeat the steps. There has to be other things going on under the hood that I can't see, and I don't want those causing any more problems than they already have.
I really don't want to end up doing a full format or taking my PC to someone to have it looked at.
