It does seem a bit ridiculous not to be allowed to save this onto a CD to protect you from a Hard Disk failure. Trouble is that the supplier is probably hoping for some support fees - who's a cynic - its certainly not (to my knowledge) a licencing problem. Have you asked Higrade about this? Drop them an e-mail or check for a user FAQ area
You will probably need a partition manager to un-hide this partition and then you can copy it to a CD or external HD. You should also test this to ensure that it will allow you to boot up to reinstall the software - go as far as the warning that it will delete all you current partition and then back out.
Re AOHell, have you tried Add/remove programs?
