The address of the wallet disappeared ... Help me please


#1

I do not know English, I use Google translator. Uploaded the wallet electrum Several times I accepted-sent coins everything was fine. Recently sent coins, the transaction in the wallet for a long time was not confirmed. Then the endless synchronization of the wallet began. I’m trying to look at my address in the explorer http://explorer.litecoin.net/address/LTmYk7kwZuW7mnfaaGRQQwnfdYqENLAMwQ
It simply does not exist … how is this possible? Below are screenshots of the wallet
