SONAR LE + LoopBe1

Hello, I'm trying to get the Aerodrums (aerodrums.com) virtual drumming instrument working with SONAR LE using the free LoopBe1 virtual MIDI cable (www.nerds.de/en/download.html). After specifying LoopBe as a MIDI input port in Sonar, no MIDI information is seen coming in. Are there any known issues here or can anyone suggest a way to diagnose this?
 
I tried it with the demo version of Sonar Platinum and everything works fine. I don't believe it's an issue on the Aerodrums or LoopBe side as MIDI-OX (www.midiox.com) can see the MIDI data coming from LoopBe just fine. I've no idea what could be wrong. Aerodrums MIDI works fine with every other DAW I've seen. Thanks!
