Hi! Thank you for the log file and sorry for the issue.

As I can see, a few times you tried to send all the amount you have in one transaction. Namely, you had 923.396 and you put 923.396 as a transaction amount, but this is not possible due to the fee = 0.001, so you can transfer only 923.395. This case is not handled in our GUI wallet, we'll fix it later. Please, take this into account.

Also, your wallet has been trying to send incorrect transactions with repeating key images. This is a very unexpected case and it's not clear how it happened, unfortunately.

I'd recommend you to do the following:
1. Make a backup (!) of your wallet keys file ( C:\Program Files\Boolberry\thanh.keys in your case ) and copy it to a safe place (usb flash drive, cloud storage etc.)
2. Download and install the latest stable version of Boolberry from https://github.com/cryptozoidberg/boolberry/releases/tag/v0.3.0.86
3. Remove or rename old log file ( C:\Users\_YOUR_USER_\AppData\Roaming\Boolb\Boolberry.log )
4. Remove your wallet data file ( C:\Program Files\Boolberry\thanh, but DO NOT remove keys file: C:\Program Files\Boolberry\thanh.keys )
5. Launch Boolberry with --log-level=2 option.
You can either edit shortcut properties:

Or launch Command Prompt, navigate to Boolberry directory and type 6. Open your wallet. "Synchronizing wallet..." should appear for a few minutes. Wait until it's synchronized.
7. Try to send coins. Start with small amounts (10..50 in your case), if okay proceed to bigger.

If this does not help, please send a new log file ( C:\Users\_YOUR_USER_\AppData\Roaming\Boolb\Boolberry.log ) to me or CZ via direct messages for further investigation.

Sorry for the inconvenience! I hope wallet resynchronization with the recent BBR build will resolve the issue.
