"I/O error" does not sound good. Perhaps you have a hardware problem? I would check my harddisk with some test tools, to make sure the disk is OK..
Hope this helps...
Could you tell me about test tools? I have no idea.
I get the impression that the disk that is bad is the disk I'm
attempting to load, in the other words the fireworks is on a cd
bundled with Macromedia Studio MX.
I think that's the disk being referred to.
