Original dvds NT playing HELP!

I have just installed trial version of ‘DVD Region+CSS Free’ software from dvdidle.com on my PC. Now, NON of my original dvds are working whatever the region. Is it because I don’t use separate dvd palyers (I usually play my dvds with winmedia or realplay)? But then the drive won’t even recognise the dvds! I have pioneer dvd-rom dvd-115. Can anybody help me!!?? :frowning:
