HTAccess Error

Well, I’m not sure if anyone can help me, but I’ve installed the W3 Total Cache and BPS Security Plugins, but I’m getting an error that says “The plugin tried to edit, /.htaccess, but failed. Files and directories cannot be modified. Please review your file permissions. A common cause is .htaccess and /home2/justmik1/public_html/wp-content having different ownership or permissions.” on the W3 Total Cache Dashboard, and an error that says, “BPS Alert! An htaccess file was NOT found in your wp-admin folder. Check the BPS Security Status page for more specific information.” on the BPS Security Dashboard.

Can anyone steer me in the right direction? I’m very much a beginner with this sort of thing.
