[Plugin: ZenphotoPress] ZP doesn’t show albums on pop-up

I use lates version of ZenphotoPress and when i try to add a picture in a post ( picture hosted on the zenpho application ) from the Zp pup-up button the album listing is empty.
I got 2 albums there and zenphotopress is not listing any of them.

I tried using the shortcode [zenphotopress] but still nothing.

I got these as debug messages and if i go on that specific pages i can see some listing :

a:2:{i:1;a:4:{s:5:”value”;s:1:”1″;s:4:”name”;s:28:”Sesiuni Foto “;s:8:”parentid”;N;s:8:”children”;a:1:{i:2;a:4:{s:5:”value”;s:1:”2″;s:4:”name”;s:32:”Alex & Andreea – 2009 August”;s:8:”parentid”;s:1:”1″;s:8:”children”;a:1:{i:3;a:4:{s:5:”value”;s:1:”3″;s:4:”name”;s:14:”Family Frames “;s:8:”parentid”;s:1:”2″;s:8:”children”;N;}}}}}i:4;a:4:{s:5:”value”;s:1:”4″;s:4:”name”;s:4:”test”;s:8:”parentid”;N;s:8:”children”;N;}}

But there is no proper listing of directories.

Can you please provide some solving points ?
