Problem After the Installation

[minox]

I have linux with apache2 and php5 and mysql5
i followed the readme file
modified my php.ini and the other stuff
then i ran the install.php script
every thing went smooth with no problem
after the setup finished i want to the default page "index.php"
to get an error in the middle of the forum page

Unknown column 'c.ID_CAT' in 'on clause'
File: /var/www/localhost/htdocs/Sources/BoardIndex.php

I have the same problem.  Help is appreciated by both of us

[EDIT/Added]
I installed the 1.1rc1 instead, and everything was fine... until I wanted to go to the categories/boards. It gave me this error:
Unknown column 'a.ID_THUMB' in 'on clause'
File: /usr/local/apache2/htdocs/forum/Sources/ManageAttachments.php
Line: 567
How to fix?
