You don't need the desktop wallet to start receiving with an external address. Generate any paper wallet with a public / private key. Keep the private key safe and use the public receiving key in the steps above. Any Bitcoin address generator works and any address/private key of type bitcoin (starting with 1 ) will work on the Valorbit network.
After that one can check the balance and transactions by searching the address on the Valorbit blockchain at http://unblock.valorbit.com/
