Okay, I'm not very good at computers, but I figured something out; how to get the Singer serial registration numbers/information. I had saved the G series, here is the link

Then just change the G to what ever series you are looking for (enter) it will pull it up. I tried the AA series and it worked. Let me know if it works for everyone. I hope it makes sense. :)
