Harven's status & a 1.5.2 error

[gillysan]

I don't use many of Harven's addons and I have heard that he uses his own library (not entirely sure what a library is). Also, he mentioned in a recent comment that his sub has run out, so I don't know if this means he is gone from the game entirely.

Harven's I have installed:
Extended Stats
Improved Skill Window
Quest Journal

There a simple fix?
