does anyone know whether the password locks. if you try too often
It doesn't lock you out even if you get the password wrong many times.
I was experience this too before when i was trying to use the portable electrum wallet i can not use my password.. i try to find the problem and wallet.dat is the problem i open the other wallet.dat to test my known password. can you try to look for
C:\Users\admin\AppData\Roaming\Electrum\wallets
and take screenshots..
Or just go to File > Open. BTW wallet
.dat is not used in every single wallet in existence. Wallets other than bitcoin core (including electrum) doesn't use .dat extension for their wallet.
