HELP!!

I'm sorry to put this here but I've tried every other route through to no avail.

I can't send PM's.

I can't read PM's.

I can't write to author, in fact this is the only way I have to point out a problem. It may be at my end - but I wouldn't know what to do about it if it is.

Every time I try and read a PM (I have a new one), I get the mailbox empty message. If I try and reread a PM I get the same thing. If I try and send a message to author - I've tried from one of Erin's blogs, I get my sent list. If I try and read one of those I get the mailbox empty message.

What do I do?
