Can't delete manufacturers

Hello. I'm using cscart 1.3.5-SP2. We have about 310 manufacturers added. From a while, i found that i can't delete or add new manufacturers from the admin page. I tried either from phpmyadmin, there i deleted from cscart_manufacturers, cscart_manufacturer_descriptions tables, i they don't appear there, but in admin and store front they are still there. I deleted cache, optimized db, same result. Any suggestions would be very appreciated.

Best regards, Sorin
