I purchased the 2.2 license, and the email says "On Linux, copy the link, and click the “Manual Connection” button in the web UI to paste it." I did that, but it says "invalid link". My guess is that the link has spaces and other characters, which get converted while pasting into %2B and %3D and such. Anyway, how am I supposed to convert such link? Ehm, I don't have even the way to add it on command line: btsync --license Sync_Pro_Purchase.btskey was without effect.
