This is how you fix this, because the update crashed out while you were updating the updated files become corrupted. To install the files, do this. Uninstall Homeworld 2, then reinstall (make sure to turn off any firewall you are running as some interfere with the installer), then when you have finished reinstalling click on register game online. Do this at the end of installing as doing it later the update patch dose not recognise it, it is stupid but its just one of those things. Once this is done, install the patch. It should load correctly now. Now this solution is for those with the retail version of Homeworld 2. I do not help those too cheap to buy the game. It dosen't cost all that much anyway.
