Hi

When you say you 'erased it' I presume that you either deleted the TS3 files from your computer or else ran the Uninstaller? Either way, you need to do a clean uninstall in order to be confident that future installation will be successful. When you uninstall TS3 games on your Mac using the uninstaller, the game leaves behind stray files and isn't completely removed from your computer. These files may conflict with future installations. It is best to completely remove them. BluebellFlora's website provides a guide on how to do this:

After cleanly uninstalling, install the base game and patch it up to date. If you cannot update via the Launcher, download and apply the latest cumulative manual patch (called the superpatch) for Mac.

Check that your game works properly. Then install any EPs and SPs that you own, in order of release date.
