First delete the theme from your Themes browser so that any partial or corrupted files are removed from the server. Turn off any plugins you have active as well.
Then re-download the theme from Themeforest. Unzip that whole file so that you have the sub folders and files unloaded. From there, try re-uploading the flashlight.zip file like you would normally install the theme from the Themes area in the wordpress admin.
If you installed via FTP, you can do that instead.
Now try activating the theme and see if all works.
