it has been brought to my attention that some problems with new games may be caused by apache itself. Apache does not set case-insensitive on the server, what this means is that if a folder is tagged as using en-us and apache looks for en-US then it does not load the files correctly. There is however, a global fix for this that can be found here
Now no one expects every admin of a site to know how to do this, GOD knows I did not, but if you pass the information on to your hosting provider they should be able to do this for you, once this is done there should be no more problems with games, well except for incorrect submission codes etc....
One game this affected, which brought lite to the fact that the above data (provided in the link) would correct this problem
You do not have to do this as it may only affect a few games, but for all of them to work correctly, then perhaps you would want to get this done, who knows it may clear up some issues with other games that did not load correctly
as a quick fix, you can this to your .htaccess file on your forum root
