Question about Outlook Express

I have not been able to receive an email in my hotmail account since 10/24. I've sent several test emails to myself and those aren't showing in my Inbox either. I've sent to myself from other email accounts and it will not display. I do not have anything blocked or filtered that would prevent the emails from coming to the account. Please let me know what the issue is as there is nothing stating there is a problem with receiving emails, and I have seen no notifications of any issues. 

I sign on to live.co.za with my email address every second day or so. But every time I sign on, it tells me that it looks like someone else is trying to access my account and it has been blocked. Then I have to go through the whole password security reset sequence. I'm the only one using this account, I'm now really getting tired of this, if this can't be sorted, I'll have to move this address to another service provider. I'm also using Gmail on multiple devices, and never had one single problem. The usual solution in Windows Online Help section is to scan your computer for viruses - done that every time. My privacy settings in Internet Explorer is all ok. (I use Internet Explorer only to sign on to my email). Any solutions?

I have used the same email address for along time without problems. All of a sudden I can't receive emails anymore. My account is now described as "send only". I didn't consciously change anything and don't know how to change it back so I can receive email again. What do I do?
