Hi junaidifiaz,
Could you let us know your OS and whether you are using an old wallet created prior to 0.8.7.7 ?
If you come on Slack at invite.zcoin.io we would be happy to troubleshoot as we are trying to fix it right now. It doesn't seem to happen on new wallets created after.
You can also contact us at
team@zcoin.io and we will be happy to look into it as we want to get to the bottom of it.
i am using New desktop pc so no issues with speed or ram. I have turned off firewall also.its version 0.8.7.7 . I am on Newer version.
