Default Evaluating seakeeping with AQWA - How to obtain accelerations at any point?

Hello everyone!
I'm a new user of Aqwa, so i've been having a few issues related to obtaining the magnitude of the coupled accelerations of heave and pitch at some specific points of the vessel in order to analyse the level of comfort to the crew.
I've already performed this analysis on Hydrodynamic Time Response, but the results are only avaiable for the position of the Center of Gravity, (please correct me if I am wrong), but what I need is to assess them at different decks (A deck, B deck, bridge, flying bridge..) by their RMS value and/or RAO's.
I know that in most recent versions, (e.g. v 16.0) it's possible to add a connection point and get the results related to it. However I use the version 14.5.07 in which there's no such thing. In addition, I use Aqwa from Workbench because it seems more intuitive and I'm a beginner. Am I missing something out from not using the classical interface (Line, Librium, FER, etc.)?
Thanks in advance for any help. Best regards!

I tried to use the classical interface, however it's only possible after running the Hydrostatic analysis through Workbench, then the restart file is avaiable to be opened at Aqwa Line. It worked OK. After this, I tried to run Aqwa Librium, but a problem appeared. As you can see on the images, the software asks the user to save the file before runnning it (image 01) and opens the folder in which it should be saved, even setting a proper name to the file (image 02). However, when I click on the Save button, nothing happens. Consequently the file is not saved and Librium can't work because of that. Am I missing a step or could I say there's a bug here? Thanks in advance, again.
