"OKAY! i figured out the bug! this version .swf file is messed up, just redownload strike force heroes 1 from a different site and when you launch the newgrounds player goto file and load .swf and load your .swf file you got from a different site. You can now play strike force heroes 1. The game should save on the new .swf file your using. Hope this helps somebody, I've been looking for a solution for awhile that doesn't fully involve ripping the game data and running a bootleg flash player." - Raymondcole7
Just to expand on this actually smart idea, one page where ur able to download the .swf file is Kongegate. Just click the game screen and click download .swf file. My love goes to the original poster for finding out how to do this <3
