Cannot save panel

I uninstalled old version (alpha 2) and installed CVS version.
When I want to "admin/og/og_collections/collectioncfg" it redirect me to "admin/og/og_collections/pcpanel/form" where I am supposed to create new panel.
When I fill name and path and save it on next page it shows this warning:

    * user warning: BLOB/TEXT column 'pcpid_7' can't have a default value query: ALTER TABLE og_collections ADD COLUMN pcpid_7 LONGTEXT NOT NULL DEFAULT 'a:0:{}' in /home/pp/public_html/coolfords-5-x/public/includes/database.mysqli.inc on line 151.
    * user warning: Unknown column 'pcpid_7' in 'field list' query: UPDATE og_collections SET pcpid_7 = 'a:10:{s:6:\"active\";i:0;s:12:\"default_page\";i:0;s:6:\"weight\";i:0;s:3:\"did\";i:19;s:6:\"usedef\";i:1;s:10:\"page_title\";s:5:\"home3\";s:4:\"path\";s:5:\"home3\";s:9:\"published\";i:1;s:11:\"show_blocks\";i:1;s:9:\"grouptype\";s:7:\"default\";}' WHERE grouptype = 'default' in /home/pp/public_html/coolfords-5-x/public/includes/database.mysqli.inc on line 151.

After I choose layout it redirect me to root. And write this message:

The settings for this pre-configured panel have been successfully updated.

And when I want to go to "admin/og/og_collections/collectioncfg" it agains redirect me to create panel.
