Try the following process to uninstall and reinstall.
1. Uninstall Game Ranger first completely. I would advise that you use Revo uninstaller Free which scans the registry too and deletes related entries. Download Revo Uninstaller Freeware - Free and Full Download - Uninstall software, remove programs, solve uninstall problems
. After the uninstall reboot.
2. Now uninstall Adobe Flash Player using Adobe uninstaller. You already know how. Again reboot.
3. Now install Game Ranger first. I do not know whether it offers to download and install Adobe as part of its install process. If it does, allow it to install Adobe.
4. If not install Adobe after installing Game Ranger.
Check whether this resolves your problem.
