PowerDVD not working...

[daysgoby]

Hey guys
in need of some help here
I have PowerDVD 7.3 that came with LG Bluray driver.
I bought some blurays yesterday and everytime I played it, my windows 7 went to the blue screen of death.. so I reinstalled the program (powerdvd) and it kept telling me 'critical component.. periodic update.. etc' so I click yes for update and tells me it's done updating but it does the same thing.
endless looop.

I did some research online but came to no solution..
apparently, something to do with AACS??

I did the update aftter thee reinstall but there's no further update just the endless loop..

How do I fix this issue?
also I haven't played bluray for awhile prior to this and in between that time, my graphics card got updated (GTX 470).
