Zapplink doesn't pick up correctly [VIDEO]

Hello!
I’ ve problem with Zapplink in Zbrush…
After i re-enter Zbrush everything seems to be fine I can see changes made in Photoshop, but when i choose “PICK UP NOW” the changes suddenly dissappear…

When I try to Zapplink different models everything works good, I’ve only problem with this one!

Is there a way to fix that problem?

Allright, I got it it just doesn’t work with flat material (WTF)
