Hi, I have been getting an attachment from a friend each month that always opened when double clicked opened in MS word. ( have Office installed on macbook) Now since I upgraded to SL these attachments show up as VLC with DAT on the VLC icon. Double click and goes to VLC playlist but nothing happens. I know these are documents and not videos, etc. Tried to google a solution but can't figure out what's happening and what I need to do to open these monthly docs. Advice, solutions, please. MacBook (black) SL version. (not tech. minded ) thanks and have a good day to all.
