Error installing Newspaper Theme: Are you sure you want to do this

I am unable to upload the Newspaper wordpress theme I purchased. I keep getting the message “Are you sure you want to do this?” and then the theme never uploads. I have tried using the upload theme button through WordPress and through FTP. Both are unsuccessful…i have never seen this error message before. My hosting company tech support team said I may need to replace the wp-config file but I have no idea what that means…please help.
