I have same problem, with old wallet i have like over 8 k coins and after installing new one and when its synced then i have only like 140 coins why are they gone ?
IF your wallet is properly synced then your coins were on the wrong fork.
This is most likely the case
mining
30.03- 08,04 was all frong fork?
