apatters- I am running into the same problem. When you get a resolution, can you please post it here? And, for my future reference, where is the BTSync binary located on the android? The really odd thing that I am seeing that you didn't mention is that I am able to sync one folder from my android, but not another. The one that syncs is the internal SD card, the one that fails is the external SD card. Both were created the exact same way on my PC and on the android, so there are no differences there (configuration, permissions, etc are all the same). I've deleted and recreated the PC and android sync settings repeatedly, always with the same results. I've let it sit for hours or days at a time, hoping that it will finally click, but it never does. Meanwhile, the internal SD card syncs without any issues in real-time.
