Does your subscription show that it ends when you expect it to?
Can you link to ancestry via the WebSearch Workspace, ie do a search?
Can you enter the ancestry website through your browser?
If your subscription doesn't end when you expect it to, you can call their support phone number. Helping with subscription and billing is one thing that their support line actually does pretty well. (Asking them to deal with the program itself is a challenge for most support people on the phones.)
