Right guys, not sure if double posting is allowed but here I go.

After a lot of playing about I found a very simple fix to this bug.

Change the res via the widescreem mod ("setup-widescreen.exe") where PST is installed (For me it is "G:\Program Files (x86)\Black Isle\Planescape - Torment").

Backup your save files somewhere as it is better to be safe than sorry. (I don't want to be responsible if your files get corrupt or something else which is bad)

Simply request to reinstall (I did this) and when asked for the resolution use 1024 x 768 (X = 1024 and Y = 768). Also make sure you say yes to updating all the save files.

Wait a bit then you shouldn't get any error after the interaction is over.

Hope this helped for anyone who is getting a similar or the same issue as me.

Hope you have a good day.
