Error in Secondary Catalog setup

[Jkleinert]

I am attempting to set up a Secondary Catalog lookup file, and when I do the process from the HELP file "Define a secondary catalog lookup file for a project" when I click the final "OK" button I get a popup that says "The selected file is not in the appropriate format" and I can do nothing except CANCEL out of the procedure.  I'm sure this is a bug, and can be easily fixed, but from the postings here, this works for everybody else,  just not me.  I'm using AutoCAD Electrical 2013, and I have Service Pack 2 installed. 

I'm on a short deadline to get this system working, and the simple stuff is killing me.  Any help or advice would be appreciated;  I found nothing in the Knowledge base or other posts.

Thanks,

Jim

OK...  When I came back from lunch, and re-started, it worked just fine....

This is typical of my luck with computers and software in general;  Apparently it works only at certain times of the day?

Thanks, anyhow,

Jim
