Problems with LR 4.4 64 bit

<p>Lately, LR is shutting down on me and giving messages such as the following: LR encountered error when reading from preview cache; problem reading the catalog; integrity of the catalog. I have not been very successful trying to use the LR help features. Any suggestions welcome. Thanks.</p>

<p>Have you tried deleting the Preview Cache? </p>

<p>I would certainly backup up the catalog to another disk and then run some sort of disk check process, starting with checkdisk and any other utility you have.<br>

Your preview cache is generally co-located with your catalog and, since there are problems with both catalog and preview cache, the integrity of the disk sectors are in question.<br>

If you have the space, I would duplicate the folder with your catalog et als to a new folder, then use the new version until you have a chance to do some disk inspection.<br>

I suggest you rename BUT NOT DELETE the faulty folder; don't give up those sectors to be used again until you know what is going on.</p>

<p>Thanks for the input. Any other perspectives or advice? Thanks.</p>
