meta tags will not save

ok.. yes I am using an older version 1.3.9h but I have been very happy with it for quite some time now.. I have added meta tags to most of my products but I have a few new products i need to add meta tags to.. well I was doing it then i realized it was not saving them.. It would save the one I had just updated but IF I did another the previous one was gone then I left the category and came back and the LAST one I created was gone as well.. any ideas.. nothing has been added to my site as far as addons, modules, themes for almost 2 years...
I am using COWOA as well
I am filling in MT Title, MT keywords, And MT descriptions
