So I just got a Flex on Monday and have been wearing it since Tuesday. When I woke up this morning I went to my computer to sync so that I could check on my sleep patterns & it's telling me it is having problems communicating with my tracker. This is t5he first time this has happened. Day 3 of wearing it, i checked the battery, it's fine (at about 80%). I restarted my computer, restarted the app, even tried re-synching my tracker, it keeps telling me it can't communicate with it or that it's encountered an unspecified problem.

This thing can't have died on me already?! Is this something others have encountered and if so, how do I fix it?
