Hi, have encountered an error message on opening Lightroom 4 using Windows 7 Pro 32 bit.
The message is saying - Error in reading preview cache.
Suggests may fix on reopening but not! Any help appreciated as cannot use Lightroom!
You can try regenerating the previews.
Your Preview Cache is stored in the same folder as your catalog and has a name: [your catalog name] Previews.LRDATA
With Lightroom closed, rename this folder to a different name and force Lightroom to rebuild your previews when it opens. .
Rikk, you are the man! - worked like a charm, thank you for your assistance, regards.
