Direwolf20 World Save error

[CreeperAndCo]

I just updated my launcher to the newer version and when I opened the Direwolf20 1.6.4 client my world save had disappeared. I went to the saves folder and I found that the save was still there though and no matter how much I try resetting the launcher the save won't appear in the 'Single Player' world select screen and I am unable to access my world. How can this be fixed? Thank you in advance
