I clicked the start button then entered cmd which opened the command prompt. I then entered:
C:\Users\cameron\Desktop\particle-qt-8.7.3\particle-qt.exe salvagewallet
(which was the exact location of my prt wallet)
It then appeared to begin opening up my prt wallet but took over an hour before it actually opened. Once it did all my previous transactions and balance was gone. So I closed my wallet then restarted it with the same result. I even restarted my computer then reopened my wallet but its still showing no transactions or balance.
Does anyone know what may have happened and what I can do about it?
Is it syncing again? Maybe it needs more time?
For all I know, if your wallet.dat file is still there, nothing to fear
C:\Users\your_user_name\AppData\Roaming\Particle\wallet.dat
