Didn't by chance uninstall the plugin by removing all the files that were a part of the plugin from your store did you?

That missing function is defined in. Two different (but similar) files:
admin/includes/functions/general.php

And

includes/functions/functions_general.php

If either file is missing or doesn't have that function, then the file appropriate to the path should be uploaded again. The function described (zen_get_ip_address) was new to the admin side in ZC 1.5.3, so if the file is there and it looks complete, but is missing the function, then perhaps is from an older version of ZC. (Ie, the current release of this plugin I believe uses/modifies that file)
