Problem with Views module

hello folks
I just upgraded the entire system but I can not do it with views module. I can not enable it in Admin/Modules (still remains 5.x version, even I uploaded Views 6.x). Please see picture here: http://www.allviolin.com/Picture%201.png

Also, while upgrading, the Drupal Core aand Legacy modules are still 5.x). Please see: http://www.allviolin.com/Picture%202.png
How is it possible? . How can I make a new, clean installation of Views? May be removing all entries of the module in DB? But how?

This is a website about music and I worked on hundreds of articles about violin, and I don't want to lose it. Any help I will appreciate.

Thanks a lot.
