each time I try to open my lightroom, it says issues opening from previous cache, lightroom will try to resolve this when it opens next, this is becoming a major issue, Im a semi professional photographer and waste so much time trying to open from backups and other sources , HELP
Delete the preview cache. It's a folder whose name ends with Previews.LRDATA, it is in the same folder as your Lightroom catalog. Do not delete anything other than the folder whose name ends with Previews.LRDATA.
If this has been a recurring problem, you may be experiencing hard disk problems, and it would be worthwhile to run some diagnostics on your hard disk.
