GASP! My Ztools created with older versions are unreadable???

I apologize if this has been addressed previously, but I couldn’t find the appropriate threads if it has been.

I’ve made the horrifying discovery that when I load zTools I created in older versions of ZBrush, they appear as cubes in the ZBrush 4, which I interpret to mean they are unreadable.(?)

My cherished collection of zTools - gone? sob

Do I need to do something other than “Load Ztool” to render my old ZTools …er… renderable? Is there any way to get ZB4 to interpret them correctly?

Is this even something that has happened to anyone else?

Thanks for any advice!
