The registry key has become corrupt.

1.. In Regedit, navigate to this key:

|--HKEY_CURRENT_USER
|-----Identities
|--------{GUID}
|-----------Software
|--------------Microsoft
|-----------------Outlook Express
|--------------------5.0

where GUID is the Global Unique IDentifier for your Identity.

2.. Under that key, you will find the following sub-keys, among
others:

|-----------------------Block Senders
|-----------------------Rules
|-----------------------Signatures

Select the Block Senders Key and delete it. Blocked Senders will be empty,
but you can rebuild it now.

Every time I block a sender, close out my email and go back in the block
senders list is cleared. There must be a setting that I am missing.
