BTMM has been working great for me for quite a while now, long before MobileMe. I had to disable BTMM this morning to use VPN to connect to my office, and when I re-enabled it I got this error message. I have the checkbox enabled in my Airport Utility for my AEBSn running 7.3.1 firmware. Any ideas? I am going to the office now so I can check it from there. Thanks.
