Have 5,000 products in CSV fileFile has been re-saved as UT8 file in google documents and exported to CSV from excelFile loads perfectly with all fields in demo of magento store manager (except we dont want to buy it:)When trying to upload in regular Magento..keep getting error messages on column duplicates....yes we have hundreds of duplicates as the titles of products in fields correspond with different sizes, etc...no way around itAny solutions around this or any open source software similar to store manager that can do the trick.  Ready to give up and go to paid solution such as Big CommerceAlso, Uploaded a bunch of free modules/keys...of open source bulk import products from magentocommerce  but I cant find them anywhere in the main admin panel to use...there is no menu item for them anywhere??
