I had a free trial of Lightroom 5 and tried to purchase it, but page errors blocked me from being able to do this. I then got a free trial of Adobe CC. At first I saw my old photos, then the whole thing went down, and now I have a new Lightroom 5 trial, and none of my edited photos. Can I retrieve all these photos from my first trial?
Yes, you have to find the catalog file from the CC trial (use your operating system to search for it, the file name ends with .LRCAT), and then once you find it, open the LR5 trial and open the catalog you just found using File->Open Catalog
