Undo Adjust Project Settings (ASIO Sample Rate has changed)

I accidentally clicked on Adjust Project settings when the “The ASIO Sample Rate has changed:” window appeared, and my recorded audio file in the project now plays higher pitched and faster. Driver popped up because I’m using the headphone jack (Realtek, set at 44.1khz I think?) instead of my sound-interface (SSL 2+ set to 48khz). I think I even clicked on “replace”, so it seems like I have to start over, or do I? Is there anyway to undo the mistake so I can get the original back?
