Arethien: So you stated that a fresh legitimate install does not need "base_scripts.dzip"
Correction: does not need third-party base_scripts.dzip downloaded from wherever. The file that comes with the installer is the correct file.
replaced and jeggy786 stated that he has a fresh legitimate install.
His statement has nothing to do with my comment.
Call it what you will. Your solution didn't fix it, replacing the file did.
Funny, I don't recall jeggy786 stating that.
I had exactly the same situation as jeggy786. Came here searching for some other solution, but found that evasive file which jeggy786 was also looking for and provided a working download link so he too can enjoy his game.
Again. funny that, because I don't see anywhere where jeggy786 said he/she was looking for that file.
This game has sold untold millions of copies (8 million in 2014). I wonder if all that multitude needed to download your file!? *shakes head*
Stop. Just stop.
