so I tried the vTiger outlook addon but no worky

here are the following credentials I put in

Username: admin
Password: *****
vtiger URL: mydomain.com/vtigercrm


I get a Security Warning of:

Do you want to view only the webpage content taht was delivered securely?
This webpage contains content that will not be delivered using a secure HTTPS connection, which could compromise the security of the entire webpage.

I click yes and get the following error msg.

PocketSOAP objects cannot be initialize

Any suggestions how to get around this chaps?

Uncle google immediately spat out:

forums.vtiger.com/viewtopic.php?p=85110

maybe there is a clue there.
