Okay so you're running windows from your edited post and you're running the ESP1 client. Please backup your wallet.dat file from your "C:\users\yourusername\appdata\roaming\Espers" then delete and recreate the folder (you can put your wallet.dat back in your directory after you've recreated it) then relaunch the client.
Let us know if you have any issues.
i no have backup for this wallet
If you read the post I explained how to backup and recreate the folder which will solve your issue. Just go to the Espers directory mentioned and copy your wallet.dat file before deleting and recreating the folder.
EDIT: You can also use the Espers utility for your Espers1 client issues (it will let you rebuild your installation)
