Outlook Express attachment .eml error message

Hello

I uninstalled Earthlink Total Access Toolbar from OUtlook Express (we no longer use earthlink) and since then, some email attachments will not open up.  I get an error message that says .eml file of unkown type cannot find association to open file, go to folder options and select (it did say earthlink message at first, but now just unknown type) and I go to folder options to try to  pick a program to associate with these attachments, but none of them work.  How do I fix this?  I uninstalled Earthlink, so cannot get the Total Access toolbar back to reassociate these attachments.  These look to be just normal attachments, text emails, not media files.  Thank you.
