there is nuthing new i can say in personal message and if someone has same thing its better to see here so they can fix
i dont have backup its done its loss
You would think when all hope is loss you would be willing to do whatever to get it fixed. But yeah I suppose you do it your way, the pm was so I could include the link for .12 which has flutterspeed to get this synced up easier.
Something to check, download crystaldiskinfo and check your drive for errors.
here's some thing to try...
Backup wallet
Delete the fluttercoin directory under %appdata%. And yes including wallet.dat
Launch qt
Sync up the blockchain
Close qt after sync
Copy your backed up wallet back
Setup a shortcut to fluttercoin-qt and edit the shortcut
Put -rescan on the .exe so it looks like directory\fluttercoin-qt.exe -rescan
And let it rescan should scan through and then start the wallet this takes awhile
Another option in shortcut fluttercoin-qt.exe -salvagewallet
If all these fail then you need to extract the keys manually, which just send me your wallet file and can work on this as I have time. Its beyond a bct post, you can search for how to do this, which I would also need to do to refresh how to do it.
And I have other wallets that work, bit I have also done recoveries for !many other wallets, these issues are not uncommon. And I could say with all the flt wallets I run I have never had this issue
but I left one of my little guys there hopefully they will payout
