Hello, I hope some one can help me

I Just got the New Vegas Ultimate Edition and It wont let me use any of my Saves from the Regular Editon, would anyone be able to help explain why or if there is something I can do to fix


Thanks

How about telling us what happens if you try and load them?

All you've told us "It don't work." which tells us nothing at all.

Your regular saves don't have the DLC content. I highly suggest you create a new character with your Ultimate Edition.
