I'm using "7Zip". With http://www.ezyzip.com/ the load bar doesn't even start lol.
It's weird, I've just made another game (just a small one to test) and it works, but the game I want to upload is not working. What could be causing this?
I wouldn't use 7zip. I had that same problem with that format.
Delete the old game files and try it again with ezyzip. Remove the index file and upload it seperately. Put all other files in one folder with no subfolders and it should work.
Like I said Kingregate takes some time to approve new games so it may not show up for a few hours.
