Okay I'm sorry for asking again.
i have staked multiple times but the majority of the time my arrow is grey. The last time it staked it turned green said my weight was 1 and net weight was seven and i had seven minutes to wait. My arrow was green for about five minutes then I staked for the other 26 or so hours since my last stake my arrow was gray.
I have had 12 hours since my last stake. It is now 51 confirmations. It has not changed back to green but will wait because it has worked everytime so far. I have had a few stakes already. I really wish i knew what to do to help. I can only say what i have done and it was pretty easy. Made back dat file. Deleted everything including the app/data folder. Downloaded the new wallet put the backup dat file in and opened and since then it has worked. But i was having a syncing issue. Since you are synced my guess is just give it time. maybe it takes a few days to get another stake not sure. This is my first POS coin.
