Two Problems: Cannot activate plugin & Supportico interface is buggy

Here is the message I get when I try to activate my newly purchased plugin:
Fatal error: Cannot redeclare custom_print_r() (previously declared in /home/myacct/public_html/mydomain.com/wp/wp-content/plugins/gotowp/gotowp_personal.php:125) in /home/myacct/public_html/mydomain.com/wp/wp-content/plugins/gotowp_g2w/_gtwp_g2w_inc.php on line 1925

And this is the error Supportico is showing me as I try and ask for support here:

Warning: array_diff(): Argument #2 is not an array in /home/suppor28/public_html/wp-content/themes/versionlog/lib/add_post/supportico-addpost.php on line 1041
