hog 2 installation

hi all

I've got whole hog 2 with me
when I boot up it go straight into the 1,clean show 2, old show 3, load new software.

i don't know what happen but now it doesn't boot up normal anymore.

so I've download the latest version and unzip it into 2 diskette

so I attempt to load in a new sotware.
but it kept showing
'Loading....
Disk or program not found'

So I though I might have a bad floppy drive so I change another A Drive.
But still get the same result.

Please help~~~

What are the possibilities for the board to act like this?
I'm pretty sure the diskette are fine since they're new
