1) I created new wallet and made a backup.
2) I noticed that there was no address in "Receiving address" window and I created new: MSXTigm4X35U3xGk3YN8r1kUarL66yezGL.
3) I send a small ammount of latoshi to this address just for test...
Then I tryed to test my backup:
I restored it and noticed that there is no new created address MSXTigm4X35U3xGk3YN8r1kUarL66yezGL and my balance is 0.
Why???
Also block explorer https://live.blockcypher.com/ltc/ display "Invalid Address". Why???
You have to create the backup (wallet.dat) AFTER you create the receiving address.
Blockcypher is a stupid explorer with lazy ass developers that still haven't included the M* type address for over a year. You need to convert it to the old 3* type address https://litecoin-project.github.io/p2sh-convert/
MSXTigm4X35U3xGk3YN8r1kUarL66yezGL -> 3LKKQoM6ZvE3FSzqwfNo2NW5G9je5zeSDp

Or just use an explorer that is not completely retarded: https://chainz.cryptoid.info/ltc/address.dws?MSXTigm4X35U3xGk3YN8r1kUarL66yezGL.htm
