It seems the file is too large to upload over 2mb. I think the version I worked on it was 163. The 2 files of the game that feature and ajax request to a php file are the only ones that give me the error. They were fine not that long ago when I was working on them.
I'm using windows 8 have been for all my development.
Edit: I got one of the capx files to work by loading up the backup of that file. Its not the newest one but it does have a lot of the latest changes to my game. Im still confused about what would cause this problem.
I should add that all my files are kept on skydrive(onedrive).
