Regarding Yeti 9:
When I converted this, I had the game looking to /games/yeti9_data. While that worked for me where my forum is defaulted as the root folder, it did not help if your site was
www.xyz.com/forums. In this case, the game was looking for
www.xyz.com/games. I changed my test forums around to confirm this. Give it another try. All you need to do for this is re-upload yeti9.swf.
If you installed Yeti 9 prior to this post, download the attachment again and replace yeti9.swf and all should work.
Sorry about that! It was my first conversion. Live and learn!
