OOPSWhen you get back please let me know, before I do it, that you do mean for me to "...just check the attribute of the wab for Read Only". I ask because earlier you said "The Read Only attribute should be Unchecked."
And thank you for staying with me on this as long as you have.

I meant to check the status, that it is in fact unchecked. You never want the WAB file to be marked Read Only.
If it's still Read Only and grayed out so you can't uncheck it, then try recreating a new wab by repeating the previous instructions. You'll have to delete the one you renamed to OLD to enable you to rename the current wab. Also delete the wab~ if present.
If the address book still doesn"t open in OE, go into the OE Program folder at C:\Program Files\Outlook Express and double click the WAB file in there to see if that opens.
