I am desperate to get your help.
I have upgraded my laptop from Windows 7 to Windows 10 today. For the past 1.5 years, I have been staking more than 12000 QTUMS using QTUM Core.
I installed the current version of QC and tried to restore the wallet from my dat. file (using both modes of reindex, salvage). But after I choose the dat. file and then the QC closes (closing seems to be fine), the QC does not come back with the right balance but shows 0 balance. (see the attached file)
I have more than twelve dat. files, which were backed up in different months and all of them worked fine just a month ago.
What would be wrong and what I should do?
I would appreciate if you give me advice please.![alt text](image url)
