Can't open some forum topics...

This has been happening recently... when I click a forum topic, it just redirects me to the Rubberslug main page.

Currently both of these threads don't let me access them:
http://www.rubberslug.com/board/thread/3785/ghibli--pokemon--eva-and-bebop-cels-and-sketches/
and
http://www.rubberslug.com/board/thread/3780/What-s-the-Japanese-name-for-a--Cel-Book---Where-can-you-buy-them-/

One of them is even a thread I made, and I can't open it to see what someone commented to me about. Anyone else have this issue or a workaround? I'm using Google Chrome, and have tested IE with the same results.
