I have done the import, no error. The counts in PP show the right numbers of everything. Categories and albums are seen in admin panel where they are supposed to be.
The problem is in showing member galleries, maybe I missed a switch in PP:
Nothing here (showmembers.php):
Àíþòà (Àíÿ) - My Photo Gallery
(it goes Home - Name of the forum/gallery - Name of the standard Members' Gallery's - Name of the first user by alphabet)
You can only get into a user's album through the admin panel:
Ôîòîñåò 02.09.2009 - My Photo Gallery
(it goes Home - Member - Empty space for the member's name - Name of the album)
I have done all options except the watermarks in PP DB management
UPDATE:
Before importing I deleted all categories and photos from PP (there were some of them) via PHPMyAdmin, simply cleaned the tables pp_photoes and pp_categories. Matbe that is the wrong way?
