Thanks a lot.it sync now.just that my coins are not there.
i will attach a screenshot of what i mean.the first one is the wallet after doing what you suggested,while the second one is the original backed up wallet showing my coins but stuck.
my wallet address is : BJ6x19mFrt3RSiWKT5DGruLbZ5JvD9E8LA.
From Help - Debug Window, try run "repairwallet". It will repair any mismatch.
As always, make sure you make multiple backups of your wallet to be safe before doing anything. (before & after etc)
