I recently downloaded GT LITE and gave it a try. No auto start on startup and JOIN button next to L4D2(legit steam) servers does not work either. No error messages, so I don't know what the problem is.
I decided to launch it as administrator, nothing.

Please help.

I have also tried reinstalling, rebooting, and have also checked disk just in case.

Hi roguelol,

I'm sorry to hear that you are having some issues with GT Lite. Lets see if we can get to the bottom of them.

For the "auto start" - Try the following:

1. Open the GT Lite "settings" window.
2. Navigate to the "General" tab.
3. Check "Start program when computer starts".
4. Click the "OK" button.
5. Quit GT Lite, then logout/login to your computer. Does GT Lite start?

For the "Left 4 Dead 2" issue.

- Are you using the windows or mac version of GT Lite?
- Are you able to use the "Join" button for any other games? If not, which web browser are you using?
