I have been using Lightroom 5.7 for quite awhile now without any problems. Then, several months ago I lost almost all of my images (still on hard drive of course). I then reloaded all of my images. However, starting yesterday, Lightroom now wants me to reregister every time I open it. I do not remember the 16-digit id number for either Lightroom 5 or 5.7, but the reregistration process seems to remember those numbers and worked yesterday but I also had to reload over 10,000 images. I then closed it. Today, it wants me again to registger again.
Anyone know what is going on? I certainly do not intend to register every time I want to open Lightroom. I am also considering getting Lightroom 6.0 on a subscription basis but do not want to invest in a new program if Adobe cannot help me with this issue. Lightroom support for 5.7 is non-existent, which is not good.
Thank you in advance for any help or advice.
