Custom Remote Control Driver

My company uses the Streamzap infra-red remote control to control a computer program that we created. The remote control is the primary input device for this program. The Streamzap remote we use has been slightly modified from the standard Streamzap remote (ours has fewer buttons). Picture attached. I need a driver created for this remote to simply send keystroke signals to the PC. Our current driver frequently crashes/freezes/shuts down...this occurs most often when a user is clicking back and forth between open applications. Currently, our remote will only work if our software is the active window. Note: our software was created with Flash (published as a projector file), and then compiled to an executable using Flash Jugglor. It would be best if this remote could control our software at all times (not just when our software is the active window). If this is not possible, then we would like the remote to send "global actions" to the PC. Ultimately, we are just trying to get around the problem of the current driver freezing/shutting down. We need this to work on Windows XP, Vista, 7, and 8 (32 and 64 bit systems). If you need to create different drivers for each, that is fine too. I would be glad to send you a remote control and USB infra-receiver for testing.
