I'm a couple of minor versions out of date (5.10.4 - latest is 5.10.10) so wanted to update but acymailing isn't in the list of Update sites.
My subscription is valid and not expired, it's attached to the correct url and I've rebuilt the list of update sites but acymailing still doesn't appear there so it doesn't appear on the list of available updates.
I don't remember there being a download ID or similar and I can't find one in acymailing or in my profile.
What am I missing?
