I don't have any issues with #14, and other miners doesn't have the same problem. So the error must be on your end.
Try to restart the wallet computer. Check in the logfiles of the wallet for anything unusual.
I restarted wallet and rigs 3 times in last 24 hours but nothing changed!
Also there is no unusual things in logfiles of spreadcoin wallet.
There rigs and wallet works without any problem for more about 1 month and suddenly this problem happened without any change on my side
