You probably have a bug in your display drivers.
You should try to update them.
Else, you can also try the different display options in Tennis Elbow, some changes might help to reduce the frequency of crashes.
Do you have some trouble in other games ?
About your gamepad, open the Tennis.ini with the notepad (or the .ini of your profiles), locate the [Controller] section, and below, edit (or add) these lines :
JoyDeadZone = 0.05
DxJoyDeadZone = 5
I hope it'll help.
