First of all, welcome to the Omchain ecosystem. Remember that Omchain is the people’s cryptocurrency and is not dependent on any institution or individuals.
Now let’s get back to the question, which is actually quite simple - all you need to do is add the Omchain network. If you still have Omlira in your wallet, they are now worthless 
OMC has been sent to wallets on the Omchain network in the amount of Omlira you had. So, there is currently OMC in your wallet, even though you may not see it. The only reason you can’t see it is that you haven’t added the Omchain network to your wallet.
