Lightroom 5 keeps asking for my serial number. Help me stop this madness!

I had a problem with that post. While it is pretty exhaustive, at first there was a major problem that baffled me. So if anyone is  having trouble with the instructions here http://forums.adobe.com/thread/800907?tstart=0 , here is what happened to me and how I got past it.

My problem was that I had been told by Lightroom about 10 times to enter my serial number. I was so fed up on the tenth time, I immediately quit Lightroom and tried to search the internet for answers. I came across the post above but could not get it to work. Why? because the post/link above asks one to search, in a couple of different folders, for a file called "Lightroom 5.0 Registration.lrreg" (because I have version 5 of the software, your number may be different).

Well I searched and searched both of the locations it told me to look in and I could not find that file. There were no other instructions about what to do if the file did not exist.

It took me about a day to realize that the reason I could not find the file was because on the tenth time Lightroom asked me to enter my serial number, I instead closed the program out of frustration. What I needed to do was reenter my serial number AGAIN, then the file would show up.

When I realized that, I easily found the registration file which allowed me to follow the directions in the post/link above.

So the moral of the story is to re-enter your serial number before searching for the file.

I should have realized this earlier, but I was just so frustrated with re-entering my serial number, I decided I was going to solve the problem first before entering that dam long number AGAIN.

Thank you dj_paige for pointing out the article and leading me back to it.
