Hi everyone, I've been having a few problems with bitcoin core so i will start at the beginning and hope i can get help here, thanks.
It started a few weeks back, i ran bitcoin core through windows on to an external drive. the drive was playing up and taken ages so upgraded the pc and download direct to C drive . I had, have most things backed up including a few wallet.dat files. After i download the newest version of bitcore and synced the blocks i copied over the wallet.dat but the wallet would not sync. If i remembered right i went to the command line and asked it to sync the wallet and it did, A few weeks later i tried to open the wallet by clicking file Open wallet and an error message popped up (Berkelybatch Can't open database wallet.dat( dupllicates fileid ef95020000001700099f6ad130000000000000000 from wallet.dat) So after that i opened on bitcore settings change passphrase, i entered my old password, and replaced it with a new one i copied and pasted, restarted bitcoin core and now it will not accept my password, i am 100% sure it is the correct password, I have the old wall.dat files from 5yrs ago and the new ones backed up, i was looking for any input before i try to do anything, can i upload the old wallet .dat file and enter the old passphrase or is that a no no? any help appreciated and thanks in advance for taking the time to read it.

if you bought the wallet its fake. Have 4 wallets with fake passwords (i.e. forged with no keys)
