I downloaded MSN onto my Macbook. I click the icon to launch it, but and nothing happens. I deleted and re-installed, but the same thing keeps happening. Then, I tried my hand at aMSN, but the icon pops up and nothing happens too. Earlier today, I used monolingual to delete unnecessary languages. I kept all of the ones that were unchecked, as well as the necessary English files. However, I did delete these files, as seen in the pic: Was that a fatal mistake? Any help would be appreciated.
