Region Killer hates me

[General Mortars]

I have Region Killer 2.5 installed in my computer for as long as I can remember.
Never had a problem with it and it works wonders when it comes to playing the DVDs I buy from the other side of the world; my Miyazaki titles, my american films, all run smoothly in my european corner of the world; it´s great not to be confined by what market interests deem I´m worthy of watching.

Until a couple hours ago.
I was in a trip down Memory Lane watching my Battlestar Galactica DVDs, stopped for a while, went out to do whatever and upon my return, no Region 1 DVDs (75% of my DVD collection) will run in my computer anymore.

Power DVD insists on reminding me that my DVD player is a Region 2 player whenever I slide a Region 1 DVD in it and Region Killer (downloaded 2.7 a couple minutes ago) is enabled ands set to default region 1, but it´s as good as if it weren´t there.
I´m officially insane.

HELP!!!!
