My issue with the EA SPORTS FC bundle purchased on Steam for 255.92 PLN. The product was sold as containing full Polish language support, yet the Polish commentary is unavailable and greyed out.
I tried to solve the problem in a dozen ways to no avail (reinstallations, file changes, verifying file integrity, renaming audio and commentary file paths, forcing Polish commentary in the setup file settings, checking the "Registry Editor" tool, and contacting tech support).
