Or maybe the problem that Cachecoin wallet is offline for almost 2 weeks.
Yup... this is def a problem. all they have to do is delete everything but the wallet and restart.. or just start with --rescan
That I have already suggested to them, but they said they have same error. Most probably admin was busy with other wallets, so haven't tried this steps.
Today Cryptopia had own maintenance, and I hope they will try again to recompile the wallet from the beginning.
