Categories to tags converter not working. Pointing to import.php instead

I just imported my posts from blogger into wordpress. In doing this, the tags were converted to categories for some strange reason.

I am now trying to convert them back into tag using wordpress’ built in converter. However, whenever I click on the “Category to tag converter” link, it directs me to the import page “/import.php”. Is there anything i can do to rectify this.

Alternatively, could someone please copy the end of the URL for the converter page, and paste it here so i can append it to my blog URL. Im guessing that would work meanwhile.
