Are you sure you want to do this? Please try again.

Hello! II got Game Addict – Clan War Gaming Theme the other day and I cant Install it yet!  I followed the steps to install with WordPress and everytime I click install after uploading the zip file (the one that was inside the other zip file) I get this error asking “Are you sure you want to do this?  Please try again.”

Ofcourse I want to do this! hahaha  But seriously… How can I fix this???

Thank you so much!
