Litecoin core crashed receiving number gone

Hello
I installed Litecoin core v0.14.2 on my computer and bought some Litecoin via anycoin direct.
I used the receiving adress Litecoin core showed me.
A few minutes later the program crashed showing me a few error messages. Than I restarted the program but the receiving adress was gone.
Can anyone help me?

Sorry haven’t seen that one was the testnet program.
