Curiouser and Curiouser
1. You haven't received a BETA testers invitation for WordAds and your blog was in the AdControl program which has been replaced by the WordAds program - how odd. Your blog is on a domain. You haven't purchased a premium theme for it but it does have a good traffic flow.
2. The OP has purchased a premium theme (Linen) and domain. "I just got an email inviting me to be one of the beta testers for WordAds, which I signed up for months ago."

(theme - )
3. noirciplume also has purchased domain and a premium (Duet) theme. "I got an email from WordAds today as well, telling me that I have been accepted. Unfortunately my theme doesn't support WordAds. So I cannot activate it. "
