Where are General Limits Stored?

I am running 6.0.37.363 and have a question as to where General Limits get shared from.  Past Limits that I have set up are now not appearing under the General Limit list and I don't see a Limit file under the Shared Lightwright 6 Folder on my hard drive.   Do I need to recreate these limits with the recent update or have I misplaced a user file somewhere?

Thank you!
