To Moguera and bicyclemadefortwo,
for issues like you both reference, it is usually better to file a support ticket (
Submit a ticket - Powered by Kayako Help Desk Software), as issues with files are generally more a symptom of your system than something in the game itself.
Moguera: your issue is most likely due to missing files while the game installs, often due to a permissions issue. If you make sure to install the game as an admin, that hopefully can solve your problem.
bicyclemadefortwo: I would recommend deleting the data/storylines/default_storylines.xml file, and then re-installing the game. Most likely something has corrupted that file. If you still have problems loading games, then file a support ticket and there may be other things to try.
