Replacing an mp3 for a wav in Ableton

Hi guys,

Just wondering if you could help me with something.Basically I found a really cool mp3 and I started making a tune with it, more for fun but it developed onto being something really good (imo at least) and now I have the CD with the sample I made my song with. Is there an easy way of making ableton use the wav version ripped from the cd (which should be exactly the same as the mp3 as the latter was ripped from exactly the same CD as the one I have) rather than the mp3?I am sure there must be an easy way of doing this but I can't seem to find it.

Please help.

I didn't find the right solution from the Internet.
