[SOLVED] AcetoneISO instead of Dolphin.

Hi everyone!
While I was in Dolphin I wanted to mount an ISO file which I have done many times but this time I mistakely chose to "open this type of files" using AcetoneISO and the Dolphin icon on my panel got replaced with the AcetoneISO icon.
Now if I click on the "start" button ( the Mageia logo at the left of the panel ) and hover over the "Computer" icon and click on the "Home" or "Documents" or "Downloads" then the AcetoneISO application starts.
How can I fix the problem?
P.S. I have tried uninstalling Dolphin and reinstalling it hoping that it would solve the problem but it did not.
