Well..I dont think this bit of Private Keys is "advertised" as much it should be.
I kept QR scans of my addresses but didnt know that i needed Private Keys too..
I even encrypted my Litecoin Wallet with password and luckily i remembered it to unlock it ..Hate to think what would happen if i forgot it.
So,right now i have wallets on PC and MAC too (for both LTC and BTC)..it is like i can have like 100's different wallets with the same Bitcoin for example if i insert the same Private Key ..
Is that right?
Well..i fell like i rescued those coins(apart from those 0.45 BTC i just cant remember sending)..from now on will spend some time learning more about it:-)
Imagine your inputs as banknotes. When you send out money, you will send out the banknote and will get back the change.
Most wallets, internally, create a new address (public + priv key) inside your wallet (wallet.dat or other files, depending on the wallet software)
I think that your 0.45 BTC is in such place. You still have that very same wallet.dat since you did that transaction, right?
Use copy/paste and try again to get the private key for

The address you wrote may have a typo, but I can't find it now on mobile.
