Lockup with Game Control Plus by Quark

I am using the GC+ library to get Windows 7 joystick movements to processing. I then use the processing program to communicate with my Arduino microprocessor. Its a great library, awesome tutorials and documentation. My problem is it works for about 5 minutes flawlessly then my processing programs totally locks up. I cannot get the program to run again unless I reboot my computer. I am sorry I cannot follow the directions for posting code. Wow what I mess I am.

 /**
 Demonstration of using a joystick for Game Control Plus

 When this sketch runs it will try and find
 a game device that matches the configuration
 file 'joystick' int the data file of the processing folder.  if it can't match this device
 then it will present you with a list of devices
 you might try and use.  Use the configurator in the Processing-->Files-->examples-->GC+ to write a data file that is included into the procesing
 folder.  You keymap and name various functions.  These are then written down below in a code. (get matched
 device and get slider).

 The chosen device requires 2 sliders and 2 buttons.
