CAN YOU HELP ME PLEASE SOLVE THIS PROBLEM ?
I've been there.
https://bitcointalk.org/index.php?topic=602041.msg7539485#msg7539485What I did, as per advice of others here. Take that wallet.dat file ( C:\Users\Username\AppData\Roaming\VeriCoin
) , make a copy of it, put it on your desktop, whatever.
Uninstall, delete any instance of the old vericoin program on your computer (including the folder that had your wallet.dat)
Reinstall the program. Before starting the program fresh, put the copy of your wallet.dat from your desktop in that ( C:\Users\Username\AppData\Roaming\VeriCoin
) folder (keep a copy on your desktop just in case).
Allow the program to start and resync.
This worked for me, I guarantee no results, but I had the exact same error message as you when switching my hard drive to another computer, not sure what caused your issue.
Good luck.
