What do I do with these driver WARNINGS I know you have a driver function does it help in this instance

I would appreciate any advice on this this is MSO Maureen i used and one of the idle aniblocks… I use the Kinley low poly hair thanks in advance for any advice on this I just want to know if you're I think it's the clean drivers button you have is what's used in this situation…

You need to open a Drivers window and check what why the drivers don’t work. Some things that may have happened:

1. Some bone like “cb_lShin” has been removed.
2. Some property that drives the bone is removed.
3. Sometimes you must press the Update Dependencies button.
