Yes, I don't delete any file/folder, but the backups of this folder doesn't work too. What can I do?
If the wallets from your \backups directory don't work, something else is going on because it's hardly possible that all of those files are corrupt.
Basically I would take the most recent backup wallet from the `backups` dir, rename that to `wallet.dat` and start the wallet with
only that wallet.dat and ColossusCoinXT.conf in the config directory. I can't think of any reason why that wouldn't work.
b.t.w. I also answered in Slack, so lets continue there.
