I upgraded mycelium to a new version and wallet disappeared

Hello Mycelium told me that there was a new version so I clicked install on the app and it removed the older version and put in the new one. However, after the new one got installed the wallet I had that had about 12 bitcoins in it is now gone. And it asked me if i wanted to import a new wallet or something, or if I had a seed/backup which I don't have anything like that.Is there a way to get my coins back, or are they lost forever due to this upgrade?I wish mycelium would warn users that they will lose all their coins just by grabbing the latest version. That seems like a horrible bug to me. via /r/Bitcoin http://bit.ly/1NA5Q6i
