Hi Baptiste,

These files look good to me, I get:

PyMOL>rms Crystal_Rfp, Vina_Rfp
 Executive: RMSD =    0.032 (51 to 51 atoms)

Is it possible that you tried with a multi-model (multiple poses) pdbqt file 
before? If that's the case, specify "mobile_state" and/or "target_state":

PyMOL>rms Crystal_Rfp, Vina_Rfp, mobile_state=1, target_state=1
 Executive: RMSD =    0.032 (51 to 51 atoms)

See also "Notes" section here: https://pymolwiki.org/index.php/Align#Notes

Cheers,
  Thomas
