Error reading the preview Cache

Help!  When I start my Lightroom 3, the message appears "Lightroom has encountered an error when reading the preview cache and need to quit."  When I press ok, Lightroom will stop.  I don't know what to do.  I read on google that I need to go to my preferences and clear my cache, but I fear that I will lose the files I was working on in Lightroom.  I have not yet saved them on an external again.

Using Windows Explorer or the Mac Finder, go to the folder that contains your Lightroom Catalog - usually within my pictures or my folder under your user name.

Delete the folder whose name ends with Previews.lrdata. Do not delete anything else.

Now, launch Lightroom and previews are rebuilt when you browse in the library. You won't lose anything.
