Mac FH app not compatible with version of OSX?

[WolvesWoodGlen]

I haven't seen anyone saying this exact problem, so I thought I'd ask.

I have Snow Leopard, OSX 10.5.8 (from what I read, should work)
But when I try to open the app it says that the app isn't going to work with my version of OSX.
Is there something I'm missing? I know I could update to 11.whatever'soutnow but I've heard that can and will make apps like Gimp stop working properly.
I don't want to go on a wild goose chase only to find out that that isn't my problem

Hello, love. You should update the Snow Leopard then come back and see if it works.

Kool, most of the threads you are responding to are old threads
Look at the date at the very top of the post. This was made in March, so about 8 months ago.
Please since ive notice you've been responding to old threads to not bring em back

-cough,cough- Well, you see. I was trying to help them since NO one did when this was asked. Just wanted to say but -sigh- ok.
