If you’re new to Litecoin, you should probably use a lightweight wallet such as Electrum-LTC or Exodus.io. These wallets are a lot more user-friendly than Litecoin Core - which is instead a more advanced wallet for advanced users.
seems like your either out of drive space or having RAM virtual drive type issues than would be my next guess…how much space are you allowing for the blockchain? usually needs 20+GB for litecoin
on your c drive is where default tells your computer to install it so if you have enough space you should be good…make sure you have the newest wallet installed at litecoin.org version0.13.2 it will use your old folder just download it and install it and let it sync…as long as your backup is in your Appdata folder still and you never moved it then you should be good
I will ask my computerhelp to check this all out. I just cant myself.
Have bought some ltc and btc in 2013.
Now have to deal with all kinds off technical things that isnt for me.
Thx for helping, i might try again later today or tommorow
can always try downloading and syncing a wallet on a different computer and then replace your backup on that one to make sure it is a hardware issue and not a software issue…try looking into expanding your available RAM if possible
