Can't finish creating NiosII project

Hi Everyone.

I would be grateful if someone could help me with this one:

I have followed this video tutorial step by step: https://www.youtube.com/watch?v=1a_cD6FBROA
I have made the same exact connections as seen in 4:43. But when I import the .sopcinfo file as in 10:02 I get a message stating that the ".sopcinfo does not contain any cpu".
Also tried creating one of my own in a few different ways but I always end up stuck at the same point. No idea why.
Checked inside the .sopcinfo and the entry for the processor module is there.

I am sure that this may be some small default missing, which the guy on the video has set already and forgot to talk about.
Or maybe it can be some file access problem?

I have Quartus installed on the default C:\Altera location, and my projects are created under the "My Documents" folder. Have tried other folders for the project with no success.
O.S. is Windows 8.1 64 bits.

Any help is greatly appreciated.

Thanks,
Marcelo.
