Reinstalled Crackpack and forgot to save the worlds

[15Rabbit5]

Hello!
So I reinstalled Crackpack 1.7.10 because it kept crashing over and over again. So I looked up how to fix the crashes but it didn't work, so I reinstalled the modpack without thinking of saving the worlds. And now I lost all my progress.

Would be more than happy if anyone know how to get the worlds back!

If you deleted the pack then checked after deleting it and there was nothing left, then no.
