1.08 came with a fix for those afflicted with a stat-draining glitch or hack, where they could re-level their drained stats without any cost until the stats and player's level corresponded correctly again.
The problem is that a newer version of the hack has apparently been more popular on PC recently, and on the dark souls reddit every other person is suggesting to try re-leveling at no cost because of the patch. This feature of the patch has been confirmed to NOT work for the PC version... but the question is also whether or not they ever got the patch at all. There's little consensus on this and a lot of people seem to disagree.
Also, let this serve as a reminder to BACKUP YOUR SAVES regularly if you play the PC version online. On r/darksouls, there were at least 4 discussion topics within 24 hours about "how do I fix my stats?" Take the precaution or essentially risk losing your character.
