Errors in DIRECTDB.DLL or MSOE.DLL generally indicate corruption in the
message store. Start by moving Folders.dbx to an empty Windows folder. You
will lose your folder hierarchy and the lists of newsgroups on the news
servers, but it might get you into OE. Note: The DBX file are hidden files
in Win2K, WinXP and Win2K03.

If that doesn't do it then move all of the DBX files to the same folder as
Folders.dbx. You should now get into OE. Try importing the messages from the
folder you moved the DBX files to. If you can't, you can use one of these
tools to extract the messages:

DBXtract:

DBXpress: {much faster for large files}
http://www.oehelp.com/DBXpress/Default.aspx

Note: It can take a long time (days with really large folders).

The messages can then be dragged from the Windows folder back into a folder
in an open instance of OE.

I use Outlook Express 6 for email with my Windows ME operating system. I
have
one email account through Bellsouth with two email addresses. Recently I
have
experienced a problem when trying to open one of the email addresses. I
get
an error message that reads "Msimn has caused an error in DIRECTDB.DLL.
Msimn
will now close." I have no problem opening the other email address or
reading my messages from it. Anyone have any suggestions as to what the
problem is and how I might fix it?
