To make a long story short, I couldn't connect GCC to my Doser 2.1 yesterday. So I downloaded an updated version of GCC to my PC and also updated the firmware. This fixed the connection issue but now my Doser will not actually dose automatically, as is on a schedule. I can manually dose, which works fine and everything else in the GCC looks like it's operating normally. The other thing that might be a clue is that the calculated amount does not update, it is always zero now.

I'm hoping this is something simple, since I really want to get this running soon.

Thanks for any help.
