The Blocked Senders registry key is probably damaged.

1.. Close OE and then 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.

Hey all. I get this when ever I try to killfile anyone at all,
regardless of
who they are. I'm on OE6 in XP Home and this has only just started
happening. My KF only has a few spammers in it so I don't think it's
full.
Does anyone know what's going on?

Thanks
