Retrieve NEM from depotwallet

Can you advise please? I have NEM in an old depotwallet. Can I retrieve my NEM or are they lost?

Have you private key?

I have the dimwallet private key.

You should be able import it into NEM desktop wallet.
Sign up > Private key wallet, choose mainnet, wallet name, wallet password and provide private key from backup, create and login into it.

Thank you. I will do that. Really appreciate your advice. Cheers
