php parse error on fresh install

I just installed a fresh version of Constructor on a fresh version of WordPress. As soon as I enabled it, I received this error in wp-admin:

Parse error: syntax error, unexpected T_STRING, expecting T_OLD_FUNCTION or T_FUNCTION or T_VAR or ‘}’ in /nfs/c02/h05/mnt/15221/domains/sandbox.idreaminblue.com/html/wp/wp-content/themes/constructor/libs/Constructor/Admin.php on line 43

Now I can’t access the admin area at all on my fresh install.
