I was suspecting maybe it was the old version. so how do i get back the 1 bitcoin send when i upgrade to either of them ?
thanks

Start multibit, select the wallet containing your coins, then click "tools", then select "export private keys" as shown in the screenshot.



A new tab should open like the one below. Select "do not password protect export file" at the bottom of the window, then click the "export private keys button".



Click the windows start button, then copy and paste the line of text below into the search box that appears, then press the enter key to open the hidden folder containing your multibit wallet files.

%appdata%\Multibit

This is what your search box should look like after you have copied and pasted the line above into it.



Inside the folder that opens there should be a file with an extension ending in ".key". Open it in notepad and copy your wallet's private key. In the example file below the private key is the bit in red.
