I never upgraded, except from 2.2 to 2.2.1 and then to 2.2.2. I was under the impression that there wasn't much to this.
After digging, I used the same update SQL tactic to fix my ID. I was the only one affected. All else, like setting permissions, etc. seem to be working. I have no idea if this was like this from the beginning, but I seem to remember a PM link on my profile and in the dropdown in forums. Strange that the PM_LINK field should be empty for me.
At any rate, it was a fairly simple fix. Thanks for pointing me in that direction.
