i changed my wallet bitcoin adress during Receive money
As others have mentioned, more detail is required so that they will be able to assist you. I'll however try and take a shot at this.
You say you changed your receiving address, this should not be a problem as long as you did not change your wallet. Each wallet have thousands of addresses on which to receive funds. If you gave out an address to receive funds then you will still receive said funds as long as you are still making use of the same wallet as anything sent to that address will still appear in your wallet.
Most wallets will change the receiving address you see each time you request a new receiving address. This is to prevent you from reusing the same address over and over which might become a security issue. The fact that it changed the receiving address however does not mean that the previous address(es) are gone and or no longer active. They are still there in your wallet and can still be used without any problem. Any funds sent to those 'older' addresses will still appear in your wallet.
If you changed wallets then its a different story as each wallet has its own unique set of addresses. If this is the case then just go back to the old wallet, your funds should still arrive there or already be in that wallet.
Hope this helps.
