Yes the same thing is happening to me, I installed the Vbproarcade hack into my Vbulletin and when the llink is clicked on the movie does load but when you right click the file it says movie not loaded and it never loads. This has been a real bother in my forums because i recently installed the arcade hack but the dang thing doesn't work. Oh yeah, I also have Vbulletin version 2.3.0 installed...
I've been trying to kill myself to find a copy of Vbulletin version 2.2.9 so i could install the hacks I wanted to, IE the rpg, the store etc. but I don't think I will ever find version 2.2.9 nor do I think the hackers will be making an rpg or store for 2.3.0
