Newbie needs help please

Hi guys, had my Live streaming player a couple of months but never been confident enough to instal custom themes.

Hope this is the corrct forum to ask this some advice on instaling Themes from my WD Live streaming player.

I have downloaded Black mamba, I have put MY WD IP address into Google chrome and can view my WD web page, I then go to instal the Themes but it wont let me, it either says error, correct the file or Im thinking its to big, what can I delete inside the Black mamba folder to make it less than 30KBs and so the Blackmamba Theme still works correctly?

Please make it simple, lol im struggling as it is with this.

Thanks
