Magento - Duplicate entry when importing backup
===

I have some serious problems with an sql backup of a shop which I only have in form of a sql backup.
Every time I want to import the backup with phpmyadmin (even on a new database), I get this error:

> \#1062 - Duplicate entry '3-249-52-0' for key 'B3A14FF699AA1FA4D4DDA0B048582A7A'

 There are several thousand products and almost a hundred of categories I need from that file! I tried disableling the foreign key checks, but nothing seems to work. I also just took the tables with the prefixes "category_" and "eav_" and put it in a seperate sql file, but the same there.... (I also could not find " 3-249-52-0 " or the key in the sql file)

Anyone got an idea how to fix this?

Thanks
