If you completed the Extract, All the icons should have changed. Let me know what happens if you try it again, and what system are you using? PC or MAC?
Running on a PC. Still getting the file is corrupted mesasages. If I try to run the Game file, it tells me "Error, Your browser does not support Web Audio API"
EDIT: Tried it on my housemates Computer, he has the same errors, but he can't extract the program at all.
Okay thank you, just wondering do you have "Drop Box" its the compression program I used to turn the file into a zip file. I just downloaded the zip file again and it worked but maybe because it goes into my "Drop Box"
