Cannot assign game to a category.

Hi,

I have just installed 2.5.9+ version on vbulletin Chinese version. Though I can create categories in Arcade setion of admincp, in edit game list, I cannot assign a game to these categories. The dropdown list is empty...

I want to know whether this is only with Chinese version 3.6.4? If it is, how to fix this problem?

And meanwhile, after installation, I cannot see any visible widget which can bring me to the arcade on the first page of forum. I have to put http://localhost/arcade.php to get into. Any idea about this?


Thanks
David
