HP 15-g094sa Display :: Cyberlink PowerDVD 12 Playback Error

I have a HP 15-g094sa Notebook with Windows 8.1 (64-bit) and for the whole of my day yesterday, I spent time trying to make my PowerDVD 12 work.
 
A while ago I wanted to watch a DVD, and when it came to the language selection screen and just froze when I clicked 'English'. I opened Task Manager and ended the session, then tried to start the DVD again and it still froze there. I tried a few times, but with it still not working I just gave up.
 
Around a week later (yesterday), I wanted to watch a different DVD and after the opening scenes (e.g. for my FRIENDS DVD's it gets past the 'Warner Home Videos'  opening), when it's about to go to the DVD's main menu, it comes up with the dialog box of 'PowerDVD12.exe has stopped working' and a crash report of 'Cyberlink PowerDVD cannot play back inserted disc. Code = 0102':
 
I tried to replace the files within the Cyberlink folder from my sister's HP laptop, but all I got was it having audio, no display, and the 'minimize, maximize and close' bar not being there.
 
I tried doing System Restore back to the 7th, which would just mean I'd get the original files back, but not far enough to the date it froze, but after that I got the message that it was unsuccessful due to my antivirus, I tried two other times with disabling my antivirus and both antivirus and firewall, but it still didn't work.
 
I uninstalled it from the Control Panel, and went to 'HP's Software and driver downloads' for my PC. I downloaded the recent PowerDVD 12, it went past the FRIENDS menu screen but played only 5 seconds of the disc before it gave me the error message again.
 
I tried to install later versions of PowerDVD 12, but this did not work. These are the versions (in purple) that I attempted to install:

Browsing the forums I tried the HP System Recovery to reinstall it, it still didn't work.
 
(I noticed that when you install PowerDVD, it asks about loading/scanning files from my computer, after pressing 'next', it loads PowerDVD's home screen, and the loading symbol for the loading of my files freezes for a bit, then the error message appears.)
 
So now I'm completely stuck on what to do. I tried with other discs to be sure, but my Twilight DVD's go past the opening credits, but never reaches the main menu selection screen.
