sorry for late reply. hope you had a backup copy of the word list. try re-downloading and extracting again, but to a different folder. that way it should use a new batch of assets. the save games are stored in an alternate location and should still be accessible, these are really just config files to set up the world state once youre loaded in and shouldnt affect main menu assets. This will have the unfortunate effect of you needing to completely set your custom settings again, including the word list, but should get you working. after you know you're up and working and the new download can access the save files, just delete the old game folder. this is a bit hamfisted but is the easiest thing to do quickly.
