I've paid for LW pro, but have the same problem originally posted by Simon Peters
the warning comes up that the application programme that created it cannot be found. I am rapidly losing my patience - any suggestions? The Mac is an iMac running OS9.2

But the answer that worked for him won't work for me:

What happens when you drop the .bin file onto the latest version of stuffit expander? Might the ability to unstuff .bin files have become unchecked in the stuffit expander preferences? If your stuffit won't expand other .sit or .bin files, perhaps reinstall stuffit?

I've tried downloading stuffit (I have the feeling it's somehow been deleted from my computer) but have the same problem with it as with LW as in it won't open/run/expand or whatever. Nothing I download will open! Please help!!
