i uninstalled the linkpoint module via the admin section. i removed the entire /includes/modules folder via ftp. i uploaded a new one and installed the module via the admin section. i tried it and got this error:

server responds: unable to use client certificate (no key found or wrong pass phrase?) ErrNo:58 server responds: FAILURECould not connect.
Warning: Cannot modify header information - headers already sent by (output started at /home/XXXXXXXX/public_html/zencart/includes/modules/payment/linkpoint_api/class.linkpoint_api.php:178) in /home/XXXXXXXX/public_html/zencart/includes/functions/functions_general.php on line 44
