, I use Perfect Disk 8.0.
I would simply uninstall/reinstall ZA, since the problem probably stems from a corrupted file in ZA.
Your system probably hangs for the same reason...try the uninstall/reinstall and see.

Not sure what you are trying to communicate here...but the fact is that you don't have use ZA at all, there are alternative free products available to all of us that do as well or better than ZA, IMO. Your decision to use it can only be changed by you.
