loading the page failed. unknown reason

well we've been duplicating our nopCommerce file system and database to a new local machine for testing, but there whenever we try to filter in category page we get this alerted message, the admin log says in short:
" Invalid column name 'ProductAttributeID'. "

and the long version says:
"

Hi inahmias,

Did you have this error on your other machine?
If no then probably there are some differences between the two i.e missing files, different database or different SQL server configuration.
