Yes:
Step 1: Delete the preview cache.
That's it!
So, the trick is to find the preview cache.
This document gives location:
http://helpx.adobe.com/lightroom/kb/preference-file-locations-lightroom-41.html
To be clear: it's a folder in with your catalog and you want to delete the whole folder but nothing else.
If your catalog file path is "X:\My Catalogs\My Catalog.lrcat", then the preview cache "folder" will be:
X:\My Catalogs\My Catalog Previews.lrdata
So the trick is to find your catalog file, and since Lr won't open your catalog and run, you can't use it to find out.
But you should be able to find it by searching your disks for *.lrcat files - do you know how to do that?
Which OS?
If you know the name of the catalog it will help, but also: it's probably NOT in with your program files.
UPDATE: The above-mentioned document gives default name and location for preview cache, so if you haven't overridden the default, it should be right where that document said it would be - is it? (of course you need to know your user name too, but presumably you do, no?).
