I didn't get any Bug Report from you...
Did you click "Send" ?Anonymus1999
no, Modding support is very limited ; you can install 2D Courts, sound mods and edit the player & tour bases for now ; check the TEM2 Modding SDK here : topic11-31376.php
try to re-launch the Patcher, if it does nothing, then you'll have to download the full install from your License Key email...
The game closed correctly before the Patcher did its stuff ?
Could you send me this folder : "C:\Users\[YourUserName]\AppData\LocalLow\Mana Games\TennisElbow4-Launcher" ?
