When I installed BTSync 2.0 it started a pro trial. I only have one folder to sync between my two machines and so I did not buy and let it expire. That was three months ago. There has been no sync between my two systems in the last three months. I have tried everything including deleting and reinstalling which caused another pro trail, where syncing works. When that expired, all syncing stopped. So what is the deal. Cannot I use this for free? I have one stinking folder to sync. Make it work like promised.
