Pop up's in Media Player

Hi all, it's been a while.
I had big problems with my p.c and ended up re-formatting. I've just found this site again and got K++ version 2.4.3 back again, but when I've downloaded a video clip and try to play it, I get a pop up in the media player telling me I need a key to unlock the clip. It tells me to send an S.M.S for the code £1.50!!!
Before my computer went down, I could download and play clips all day!!!
Anyone know whats going on?.
Or is it a case of just more junk/fake files on p2p??
Thanks for any answers in advance.

delete it, add WMA and WMV to your search filters.
most are copy protected with DRM.

Ok. Thanks for that. I will give it a try. I've come to the conclusion that Kazaa is pretty screwed now days...sooo sad.
Si.
