My litecoins are not showing up in my wallet

Hi there

Could somebody please kindly advise -

My Litecoins are not showing up in my wallet.
The wallet I have is: Litecoin QT Version V0.8.5.1 -beta

Other messages appearing in my wallet are:

‘Alert key compromised, upgrade required’
‘Wallet (out of sync)’
‘Recent transactions (out of sync)’

Do i need to upgrade if so, how to do this ???


did you ever had litecoins there,. do you know the public key (address), to check if the coins are still there.
