The Prequel total conversion mod not working with JA Enhanced is a known compatibility issue. JA Enhanced modifies the game engine in ways that aren't always compatible with large mods like total conversions. You might need to use the base Jedi Academy executable or OpenJK instead. Also, make sure the mod files are correctly placed in the base or mods folder and that no conflicting PK3s are loaded. Hopefully future updates will improve compatibility between the two.

If you're encountering a Crash on startup with the error Couldn't compile shader, it's likely due to outdated graphics drivers or incompatible GPU hardware. Make sure your video drivers are fully up to date. Also, check if your system meets the game's minimum requirements. Disabling mods or adjusting the graphics settings manually in the config file might help. Reinstalling the game can sometimes resolve shader compilation issues.
