Thanks for the advice.
This address is no longer usable as I have lost the redeem script. Someone sent some 300 bits to the address but I think it is lost forever... It has effectively became another bitcoin burning address... sigh..
I will try again to generate another throwaway address and will play with it, before I actually generating a real address.
I would recommend that you try your testing on the testnet. You can get testnet coins from a testnet faucet and those coins are worth absolutely nothing. Those coins are free and always will be, and are perfectly safe to lose.
