Did anybody have any issues updating the firmware with their unit? I purchased one and I've tried for 2 days to update the firmware but all I get is the loading message and it never seems to finish. I shut down my PC and started again and it will connect to my PC and sync my courses but it will not finish the firmware update. The first time I tried I let it sit for 21 hours and it still didn't finish apparently. I tried again today and was able to sync my courses and it says the last update was today (4/16) but it will not get past the loading screen. I've sent an email to Shot Scope to see if they have any ideas.
