My Team Fortress 2 or any other game on my steam dosen't work because of gametracker. I've tried uninstalling it but it says "Shutdown gametracker first" and i don't see anything on shutting it down! Please help

After you uninstall your GT Lite you need to restart your PC. If you are still getting this error then try to remove GT Lite Client manually from your Program Files folder.The another possibility is the GT Lite process is still running in the RAM. So, open up the task manager and search for the GT Lite process and kill it.

Can you please take a screenshot of the error message regarding GT Lite and describe in more details the errors you are experiencing with your game?

GT Lite can be minimized to the task bar. You'll need to make sure to fully close it before uninstalling it. Exit it from the task bar or within the app. If it is still running, you may need to manually stop it from the task manager.
