Can’t download files

I added my old outlook express to Windows Live Mail.  I can log onto this account.   I am told it needs to download my files from outlook express before I can use it.  I get a message telling it can't download my files for the following reason:  the connection to the server has failed.  Your IMAP command could not be sent to the server due to non-network errors.  This could, for example, indicate a lack of memory on your system.  Code 9800cccOe.  I just bought an 8.oo GB memory computer with Windows 7 so I don't think that is my problem.  Wondering if anyone else has had this problem as I am searching for an answer.
