Help with iframe code

[websitedude]

Hi, my site is a free online games site where we develop our own games. Untill recently all our own games worked fine being put on the site by opening them in java and extracting the exe from the zip folder. Now an error comes up saying it cannot find the file but if you look in the iframe code and copy the zip you will see it is in the right place.
One example:
http://igames.org.uk/WWII_Ground_Defence.htm

Help please
Thanks

When I open the URL (http://www.g-java.com/gmbed/getgame...roundDefence.exe&width=640&height=480) used in the iframe in the example page and the URL for the page it references (http://www.igames.org.uk/Files/WWIIGroundDefence.zip&exe=WWIIGroundDefence.exe&width=640&height=480), I get a 404 response for both.
