Hi all first post here.
I paid for a years subscription on the 5th March, today it came up with a message in red on the top of the screen saying 0 days of subscription left and uninstalled. >:(
I re-installed from the email and it is now saying that I have a trial version which has run out!
I have sent them a ticket but thought I would ask here as well in case anyone knows what to do as I now am without anti-virus and that makes me a little nervous. 
Thank you !
