I've got BTsync installed on my Windows 8.1 laptop and my Synology NAS. However, it fails to sync. On my NAS, BTSync indicates that 1/1 peer is online, that is is to get 551 files from my laptop (2GB), but nothing happens, and it has only synced 2 MB thus far.
My laptop contains the folder that I want to sync to the NAS, which is about 300 GB large. BTSync indicates that 0 peers are online.
I have opened upnp on my router, re-installed BTSync on the NAS, re-added the folder, but nothing helped.
The log on my laptop shows, with some repetition, the following errors:

I cannot find any additional information about the 'mutex' error.
When I created another folder (the 'TestSync' folder, empty on both laptop and NAS), it worked for a little while when adding new files, but it also has stopped syncing now. (Also 0 peers according to laptop.)
To me, it seems that connectivity is not an issue, as both systems (at least initially) detected each other and synced some files. Any ideas are welcome!
Cheers!
