Themes aren't showing up on Multisite

Hi,

I'm kinda annoyed with Multisite.First of all, I'm having trouble getting the other themes to show. It only shows one theme but when I go into FTP, I had several. When I check the WPMU plugin, it said that I had several themes installed.

I know I've messed up on something but I don't know where.

Please help.

Virgil
