I certainly don't see how I could have gotten from Avast to ARO 2011 - because Avast was what I was shooting for. I've used the free version and it's very good.
Thank you for your info and hope I can get out of this mess. I'm calling them tomorrow and since I haven't downloaded anything - hoping they will give me my money back.
Since I bought through Paypal I can file a complaint with them too....
Thanks for your reply.
