I have recently switched PCs and I am trying to get my litecoin wallet over to my new PC. Now I have an issue starting with my old PC, where Litecoin Core keeps crashing. It gives me a MinGW Runtime Assertion error message:
Assertion failed!
Program: C:\Program Files\Litecoin\litecoin-qt.exe
File: validation.ccp, Line 2366
Expression: "setBlockIndexCandidates.empty()
If I click on “Retry”, the runtime terminates the program.
I had not backed up my wallet.dat file and when I now try to replace the wallet.dat file on my new PC, it gives me the same error. I have since uninstalled Core on my new PC, wiping all data, and reinstalled it to have a new, functioning, albeit empty wallet.
Back it up how exactly? I have it saved on a USB, but when I replace the wallet.dat file on my new computer with the old one, it gives me the same error message on my new PC. Could the wallet.dat file be corrupted somehow?
First of all, thanks for your help, forgot to say that in my last reply! Appreciate you taking the time.
The time of the backup matters? What time should it be? I have backed it up about 30mins ago. I still get the same error message on my old PC when trying to open the wallet.
When replacing the wallet.dat file on my new PC, should I first let the wallet complete the download of the blockchain?
