ok so i downloaded last moon, and waited about an hour for it to finish, then i installed it. i clicked run and the game showed up on my desktop, so i of course clicked it. the screen showed up and it said: checking for new updates. as it was going through the updates, i had to take the dog outside. when i came in a message on my screen showed up and said: this file is missing (i don't remember the file name but it started with a lower case d.) then i clicked ok on it and another message about OGRE came up. so i double clicked the last moon icon and it said checking for new updates. then it closed itself out! i waited an hour then came back and it still did the same thing. can someone help me please?
