LiveMail- Accidentally blocked myself, then unblocked myself but now not getting emails

While deleting junk mail in livemail 2012 on my laptop (and adding some senders to blocked lists) I think I accidentally blocked my own (live.com) email address as I stopped receiving emails. When I checked the security options in livemail, I found my email address in the blocked senders list and removed it. I also manually added my email address to the safe senders list. I'm still not getting emails on my laptop but can see them, in the outlook browser and on my iPhone, so it seems to be an issue with livemail not wanting or being able to retrieve them.   By the way, I actually have two live.com email addresses, the one I'm having issues with is private and my other unaffected is a work one.  I've checked the properties of both and they are identical.  All the synchronisation settings are correct too.  I even added myself to my contacts hoping livemail would accept me as a safe sender but I show there as offline even though I am logged into Microsoft.  I've restarted Live Mail and my laptop several times while trying different things. Any ideas how to fix this please?
