Do I have to buy all of the guides to use new functions

[dkardell]

If I have 5 guides do I have to update all 5 in order to use the new function, or will the old guide data work?

I have Guides 1, 2 and 3. If I update Guide 1, what happens to Guides 2 and 3?

Zygor Guides 4.0 and all its functions will be released as a free update to all users. Any guides you don't currently own will ship with trial versions of them as well. Some features will perform best by owning a particular guide, and these are:

Gear Finder: Requires Dungeons and Gear guide for full database of gear.
Creature Detector: Requires Pets and Mounts guide for full database of pets/mounts/hunter pets.
