Last night I upgraded 2 QNAP NAS to v1.4.76 of BTSync (from 1.3.106). I'm encountering different (critical) problems with both installations. The first install is on a QNAP TS-670 Pro. This NAS has 22 BTSync shares. After upgrading, the BTSync process stops ~15 seconds after I turn on the service. I've restarted the service more than 10 times but within a few seconds the process ends without any indication why. The second install is on a TS-212. This was a new install of BTSync on this NAS and I'm just creating my first shares. After upgrading, I'm trying to create a share using an existing READ-ONLY key. After entering the key and selecting the folder, no peers are listed. When I display the keys of the sync, neither the READ-WRITE or READ-ONLY are the same as the READ-ONLY key that I entered when creating the new share. BTW, last night I also upgraded my two NetGear ReadyNAS 102 to BTSync 1.4.77. One has 8 shares and the other has 9 shares. Neither is crashing and I'm able to create a new share using an existing READ-ONLY key. Questions: 1) Is anyone else experience the same problems on their QNAP NAS? 2) Is there anything I can do about these problems other than wait on an updated version? Thanks... Alan
