Problem with tables & columns in vendorprofile & profilevisits

Hello!
When I was clicking vendorprofile &/or vendorvisits I was having this 1146 error messages, that I don't have "community_users" table & I need to create it. So I did, and put there 4 columns with names: id, first name, last name, user name. Apparently it was wrong, cause now I'm having this 1054 error messages, but I don't know the exact number of columns & their exact names, how it should be. So what should I do & why I'm having this problems, why VMVendor didn't create this table itself?

Plus, when I'm switching the vmvendor features on to English, I'm having another 1146 error message, which shows (according to my server support team) that I don't have "virtuemart_manufacturers_en_gb" table. Very strange. Before I install VMVendor I didn't have such problems. What should I do & how can I create this "virtuemart_manufacturers_en_gb" table, I mean, how many calumns & their names?
