when I try to edit this on quest game it says file cannot be loaded invalid ID why does itsay this I tried playing the game and it worked so help me out here

Is this online or using the offline editor?

Open the game in notepad, and post the first 5 lines...
Like this...

<asl version="550">
  <include ref="English.aslx" />
  <include ref="Core.aslx" />
  <game name="Wumpus">
    <gameid>0f232c7a-8772-4a4b-85c3-075cd682ef3a</gameid>
    <version>2.0</version>

The problem would be the asl version or the gameid...

The only thing I can think of presently is that games created offline are given an ID (which is used for publishing online by the database). If you try to publish two games with the same ID you'll run into problems when trying to upload the second one (there's an option in the offline editor to generate a new ID in the game setup tab IIRC)
