Answer 1

Cannot find XML::Entities

Can't load SOAP::Transport::HTTP*

See prerequesites for installation : everything is on wiki or on tutorials (it's really easy to find tutorials ...).

I'm not sure due of lack of informations : if you want help, please give more (and more) informations ...

EDIT : There is here 2 questions with IPDISCOVER_LINK ...
