Based on this thread:

Now I still can't be able to download PDC 2010 slides! I'm very sorry I have to "reopen" this.

Please, pleeaasseee fix this.

FYI: I can't download on site, and it'll always redirect to this channel9. I find it very strange when I can download PDC 2009 slides, but I can't download PDC 2010 slides. Sad
