Girder not seeing Firefly receiver (Win7 64bit)

[RandomEvents]

Simple issue, girder isn't seeing a Firefly receiver with x10 drivers installed. Window does register it, with the wireless remote dialog in control panel, and the control panel dialog registers all key\button presses. The dialog also registers when I use my old remote wonder remotes. If I use the old remote wonder receivers, girder works for both remotes. I'm not using any drivers but the x10 drivers 64 bit drivers. So far I was lucky enough to have 3 remote wonder receivers to pair off with each of the new firefly remotes, but that doesn't seem to be an option going forward if i want to more remotes to the other systems in the house (what can i say, i do like the ability to program a channel into the new remotes, as opposed to the lock on channel 16 on the old remote wonder remotes).

Any help?
