Points going down when downloading a game with no point cost

I downloaded a few games the other that had a 0 point cost, then after an hour or so I lost a bit of points.Was it a glitch or were the point costs not mentioned?Games were: Lunar, Lunar 2, Star Ocean for PSX

I think that you must have read something wrong...I just checked those games and they all cost points. :(

It appears so now, however 2-3 days ago it was showing a 0 cost for them...

You probably checked after you started the download, once you start a download the file's point cost is set to 0 for 24 hours for you only. This is so you can redownload if something goes wrong. Once the 24 hour period is up it will reset it self.
