Its look like its working now.
I can use also my old wallet with the new reward cut?
I want to update it, just a question, thx for reply.
No I read it's a mandatory update, you
need to update.
So I update it now, @Jahl already told me just start it from new folder and all my coins everything is still there without doing any other things?
You should backup your wallet just in case.
1.Shortcut WINDOWS+R
2.Type %appdata%
3.Look for LitecoinDark folder
4.Backup Wallet.dat
5.install new qt, replace the old one or make another folder
6.Run wallet, coins should be there, if not, you have backup.
