Thread titles don't show up

[tdomex]

When viewing a forum (example: http://ak-47.gunsnet.net/vb/forumdisplay.php?s=&forumid=15), thread titles don't show up (table cell is empty with no text at all). They do show up when viewing a single thread.

Tracked the problem to AdSubtract... I turned it off and the titles now appear in both IE & NS.
