UnintensifiedFailure To replace the files Walt mentioned right click on the link and select "save link as.." (or "save target as...") then go to "C:\Program Files\Cosmoteer" in the "save as" window and save the files there. This will replace the files that are already there which have the same name.
Note: Walt is the game developer so if there is anyone that can fix this it is him.
(Also, don't make duplicate error posts.)
