I know I've seen a couple people have this problem but I'm not certain I've seen a resolve for it.
Every time I try to install a theme on my X, whether it be through the toolbox or through the forums, it downloads alright but when I go to install them it says it can't open the zip (bad). Again, I apologize if I've missed the fix but I've followed installation instructions carefully. I did get one theme to install a while ago which was the blacked out blue theme but I'd like to try different ones. Any help is much appreciated.
