Cant backup my FlyFx disk

[videofx]

I have tried both index and splice and 5 different brand new floppy disks and get the same error when I try to run the copy. I get READ ERROR ON DISK BLOCK 1457

I know the disk is copy protected because when I make a disk from an ADF and run install it keeps asking to insert DISK 1

Please help as this disk is NOT available anywhere should something happen to my original

Oh and I'm running version 1.20 and firmware .90

Thanks!
