Does anyone know why the "develop" tab along the top of Lightroom app will not allow me to click it open? Perhaps because I am using the free 30-day trial it will not let me edit the photos extensively? Please let me know! Thanks.
No your 30 day trial is fully functional.
Make sure you create a catalog and import the images as you cannot work directly on the file system. LR is a non-destructive editor and as such needs the images referenced in a catalog before you can work on them.
Thank you for the quick reply - this helped a lot! I just had to create a collection.
