How do I keep my saves when using newer version of dolphin?

[Sikker]

So I downloaded an old version of dolphin a few days ago, and played Fire Emblem for abit. Now I downloaded the newest version and when I play the game on that version of dolphin, all the saves are gone. Both the save states and the normal memory card saves. So does anyone how to use my saves in the newest version?

Thanks.

edit: I tried copying the save states and memory card from the user map, and while the memory card works, the save states dont and it says "can't load state from other revisions."
Also Im getting some very strange bleepy sounds in the newest version, how do i fix that?
