Ah. I see. Were you using a free version? Free versions always come with some limitations, with some of the program's functionalities disabled, usually some advanced features that may or may not be necessary for an average user.
It's how software companies make money. They give you the basics, just enough for you to get a taste of their stuff, but don't say they locked out some parts of it out which will remain locked out until you cough up a few dead presidents and enter a registration code they give you.
It's a clever and very devious tactic. File recovery software comes with similar restrictions in their free versions. They allow you to run a scan for lost files, list everything they find and ask you if you'd like to start a recovery process. You click
yes, and a new window pops out, informing you that recovery itself is not possible with an uregistered version of the program and asks you to buy a license, a registration code from the author(s) if you want the program to actually do what it was designed for.
Geeky bastards.
