Unespected error in DPARFSA

Hello to everyone.
I'm trying to use DPABI to preprocess some structural and resting state data.
I would need to spatially normalize both structural and functional to a template made on this specific sample of subjects, in order to later perform some unsupervised clasification.
However, I get the error in the screenshot attached.
I also attach the screen of the settings I used which generate the error.
How could I solve the problem?
Thanks a lot.
The problem seemed to be due to the fact that SPM was added with subfolders.
