Nikolay, my file was submitted via the Bug Submit form. Note that the bug tracking system that is being used by NV employees is not public yet so I cannot send you a link.....  you're not the first to refer to it in a post.     ptoner, these are the links to the preference reset instructions that Tech Support sent me -      VW2018 has required multiple resets in the first month and a bit of use.... far more than any other version.   Kevin
