Glide Grid Reader error

I have created glide grids for 3 protein files. At first I tried to connect this node to the ligand docking but I receive such an error:

java.io.FileNotFoundException: Output file ‘/var/folders/ns/gqxxqqwn54bbpdz2t3z0dz24q5yzqp/T/GlideLigandDocking1411856320pv.maegz’ does not exist.

Then I tried to save the grids and import them manually into the workflow to see if the problem will be solved but now I have problem with reading back the grids!

I don’t understand where I am wrong?
