Hi, Anthony,
i have same setup. Also tried to install 5.2.3 drivers and got the same problem. Than just reinstalled BM drivers to 5.1.2 version and Multibridge Utility to 1.52. Everything fine now. It seems like 5.2.4 drivers think that your Multibridge is the Multibridge Extreme and something wrong with it. 🙂
So, try to revert to older drivers.
