@DahliaW Are you still having issues getting the game running? If so, please do a clean uninstall of the entire game, as described here:

Install the base game only, and run the Super Patch (digital download version):

Test to see whether the patched base game opens. If you get an unknown error, let me know. If you get the license server error, just ignore it, and go ahead and install your packs. If you get an unknown error after the packs are installed but not before, please list all the packs you've installed, and any you would like to install but haven't yet.
