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.
I am not a tech guy too but what I often do is to get the private key via my email address once you send your private key it will send you an email that you should verify your account but if this fails simply look for your welcome email that block chain sent to you, you will probably get some help there.
