My podcast has disappeared from iTunes.

Hello, I made a stupid mistake and it has crashed my podcast. I logged into Podcast Connect last night and added the RSS feed etc but did so under the wrong email address. Been so long since I logged in, so I used an old one. Corrected that today: logged in with DIFFERENT email, added RSS etc. All is well: got access to the new analytics etc. However, major problems with the podcast since! Vanished form iTunes. Some listeners tell me the artwork has greyed out, and that they cannot subscribe, and episodes won't stream (although they ARE visible). Assume problem caused by me (stupidly) logging into POdcast Connect and hooking it up with the RSS feed under TWO DIFFERENT e-mail addresses. Howe can I rectify this?

Thanks.
