Hello,

I am getting problems...
Two Problems:

1. When i try to send someone coins, it says: Invalid to address: (walletaddress here to whom im sending.)
2. When i try to edit any setting, change label or create new address: Error Saving Wallet: Checksum did not validate

I tried Integrity check, I got this: Private key does not match bitcoin address


Please help, Im not able to send.
