There is something weird with your folder. The icon for the original DMMD:re does not appear properly. Did you properly install Reconnect?
Also, you did not properly change the extension that's why it did not work. To properly change the extension of the crack: go to Control Panel>File Explorer Options>Uncheck "Hide extensions for known file types."

Fig 1. Control Panel options showing File Explorer Options. Cursor pointing out to relevant window.
Then rename the ".txt" extension of the crack to ".exe". If successful you should see the text file turning into the DmmD:Re icon.
