[RCU] DB upgrading schema problem

Hi everyone i am beginning in a new place and i found a really old roundcube version 0.5.3 i try to upgrade to 0.9.4 manually but i get stuck with the database schema update, the back end is postgresql the error is

Updating database schema (2013011000)... [OK] DB Schema: NOT OK(Database schema differs) Missing table 'cache_index' Missing table 'cache_thread' Missing table 'cache_messages' Missing columns in table 'contacts': words Missing table 'dictionary' Missing table 'searches'

From the webgui i select the proper version from where i am trying to

update but nothing changes tables are still missing, any idea how to fix this.Thanks in advance.
