After Edit Library Item- "Premature end of JPEG file"

Question

Hello, I'm using Windows 7 Home Premium 64-bit.  In DW CS5 after editing a Library item and saving, DW asks if it should update pages containing the item.  I tell it to go ahead, and after some processing I get an error box titled "JPEG Library Error."  The message is "Premature end of JPEG file."  Nothing else except "OK"!  I can't imagine what this is referring to or if the error is causing the pages to not be updated with the edited lbi.  I don't have any JPEG images i nthe Library item.  Here's a link to the Libraty item:
http://www.techno-archive.com/Library/bottom_menu.lbi
After I dismiss the error in DW the Update Pages dialog sits there with the Done button grayed out.  The bottom few lines of the log look like this:
updated gallery_rec\trees\firetree\firetree-sky2.html
    item Library\bottom_menu.lbi
updated gallery_rec\trees\firetree\firetree-tree1.html
    item Library\bottom_menu.lbi
updated gallery_rec\trees\firetree\firetree-tree2.html
    item Library\bottom_menu.lbi
updated gallery_rec\trees\firetree\firetree-tree3.html
    item Library\bottom_menu.lbi
updated gallery_rec\trees\firetree\firetree.html
    item Library\bottom_menu.lbi
Done.

It doesn't tell which pages got updated and which didn't or why those that didn't did not get updated.
Any ideas anybody?
Thanks, - Dave

Update- Solved!
An answer to this thread dated April 30, 2009 of the same subject by David_Powers, community Professional, did the trick.  I wound up renaming the DW Configuration folder in C:\Users\dmckeen\AppData\Roaming\Adobe\Dreamweaver CS5\en_US\Configuration (where dmckeen is my username) and letting DW rebuild it.
