Problem importing

I am having problems importing CSV file into the classified theme. When I try to import I keep getting an error: Identifier name ‘ID,post_author,post_date,post_content,post_title,post_excerpt,post_type,category’ is too long in your CSV file.

I tried differnet ways even trying to import one record and it just doesnt want to work. What am I doing wrong?

I have wordpress 3.5.2 and Classified Theme v 4.2.
How can I solve this problem, I need the import to work it is vital in the site im working on. Please help

Thanks
