My GF and I have been playing together since release date more or less and have never had this issue until she logged in today. We are both using the same GameStop brand XBox 360 wired controllers. We played last night after the patch without any issue, but today she logged in and the game is not reading her controller at all. She will get as far as character selection and then the game stops reading controller input. Other applications read the controller just fine, and the config tool's gamepad test reads it just fine, but once she is logged in she loses it. All the while, the chat program we use to talk still reads input from her controller, as she has it set to use a button on her controller to push-to-talk. It's starting to look like it is a client side issue.

We have tried unplugging it and plugging it back in, restarting the game, restarting the PC, and checking "enable gamepad while application is in the background"... Would reinstall drivers but it is a plug and play device and other applications are picking it up just fine...

Just not really sure what to do here. ><
