Sounds to me like you are using the wrong catalog file.
Try the menu command File->Open Recent, open each catalog shown there until you find the one with your edits.
If that doesn't work, have your operating system search for all files whose name ends with .LRCAT, double-click on each one found until you find the one with your edits.
Can't still find it, have been looking through all the backups I have of the different dates, its only 5 backups so.
Sometimes, people write words to mean one thing and across the internet they are interpreted to mean something else.
So when you say:
Can't still find it, have been looking through all the backups I have of the different dates
it sounds like you (the human user of your computer) are doing the searching. I specifically want you to use your operating system's search feature to find all files on all disks whose name ends with .LRCAT. Were you using your operating system's search feature?
