ok.. before either of us lose some hair...
1) download a game from miniclip.. if you don't have a .zip file you've done it wrong.
2) open the .zip file and you should find several files like : .gif, .swf and most importantly a .html.
3) open the html file in notepad or whichever text editor is your preferred poison (wordpad/textpad

)
and copy what you find into one of the html files that you have previously used in your website.
4) upload ALL the files from the .zip EXCEPT the original .html.. and INCLUDE your new .html.
5) sit down and have a cup of tea.. sorry.. not you.. i'm doing that.. *sigh*
