URGENT! PREMIER PRO AUTO SAVE ISSUES

I have a very weird issue as well. I noticed that one sequence is missing from my project. Thinking that I might have accidentally deleted it, I decided to check the last auto-save to the point where that particular sequence was still around. After going through my autosave folder blood runs cold when I realized that my autosave folder only has the last 20 version over the course of 1 day - and the auto save version I was looking for was probably from more that 2 days ago. I noticed that when Adobe recently updated it reset the allowed autosave version to max at 20 only effectively deleting all that comes before that.  Can Somebody help me?
