We are sorry to hear that you are having issues with your Dual Action Gamepad. Unfortunately as the issue is more with the gamepad itself and not the configuration tool, we can only suggest to reinstall the driver that you are currently using and to remap the controls using the FINAL FANTASY XI configuration tool. The issue is likely to be with your current driver configuration, so reinstalling or changing versions might be able to resolve your issue.

Another option that may work is to disable any outside processes. Here is how you would do so: Press the Windows Key and "R", then in the dialog box type msconfig and press "OK". Select the startup tab and choose Disable All. Once this is completed select apply and then restart your system. After which we would like you to try playing the game again to see if the issue persists.
