I recommend redownloading the blockchain to fix the warning.
Newbie here . . . how does one go about redownloading the blockchain?
I'm still getting "Checkpoint is too old" with the latest wallet posted at OP.
Need some help~!
you need to delete everything besides wallet.dat and CapitalCoin.conf in the CapitalCoin appdata folder and restart CapitalCoin-qt to redownload the blockchain
