Query: Didn't work, messed up other software and computer

I installed this software package on my year-old computer, but when I tried to start it I just got an error log file to be emailed to Garmin. Their tech support department was closed. Worse, another Garmin software package (MetroGuide) had now stopped working, and the Windows Uninstaller kept crashing when I tried to remove them. A good hour and a half later I have finally reinstalled MetroGuide and made it run, but USA TOPO is going back to the store. I already have enough things that don't work!
