Sorry. I didn't see that folder in the beginning, as it was hidden. And, in Windows 7, you can't access that folder directly. Instead, I have discovered, that you have to go to C:\Users\{Your Name}\AppData\Local\TopoFusion. That is where the TopoFusion.ini file is for me and I can actually get to it. I renamed it and that did the trick! Thank you!
I noticed the file after roads-large.gpx in the .ini file was wilderness.gpx.
