Hey CryptoJohn, hope you're doing well. Everything appears to be running normally.

I would recommend resetting your blockchain. Make a copy of your C:\Users\USERNAME\AppData\Roaming\DNotes2 folder, then delete all the files in that folder except for the wallet.dat file, and open the wallet to start downloading.

Another thing you can check is if your inputs are getting to small, you can click on Send, then Settings > Options > Display and check display coin control features. Then click on inputs to see the size of your inputs. Likely any inputs for each address under a couple hundred DNotes would be too small. You can select inputs from one address, make that same address the change and the receiving address, and send your coins. By using the same sending, receiving, and change address, you can maintain your CRISP payment while merging your inputs.
