style table error
 

Hello everyone,
I'm facing a strange error in db. when I try to create a new style it always takes the id zero (styleid=0), and I get this error (you cannot assign main em>stylename to one of its branches ). but the style is created anyway. this is the case with creating a style without parents.
if I create a child style, I dont get that error but the id will be set to zero too.

and If I try to delete the new style with id=0 from admincp, I get and error says: there is no style with id=0. thought, it's still shown in admincp.

I tried to use tools.php to repair the tables and the style, but it didn't work.
I tried to run upgrade, but it didn't work either.

repair table gives this note: Table does not support optimize, doing recreate + analyze instead
after I create the style with id=0 I get mysql errors in all sections of "Styles and Templates":

Moved to vB4 section.

Check Maintenance > Diagnostics > Suspect File Version. Are any DEFAULT vbulletin files listed as "not containing expected contents" or as "expecting version 4.2.2, found verion 4.x.x" ?

Go to your phpmyadmin and check the template table and see the title table and see if any are empty

I didn't find any file with "not containing expected contents" or any other notices there.
also with the templates I didn't find anyone with an empty title.

You did check all pages as i have over 100 and only have one skin installed
