[0.5-Beta] Address Book vCard Import Problem

[d.e]

All,

I'm hoping someone can help with a address book import problems I'm having.

I am using roundcube 0.5-beta, on Windows Server 2008 with Apache 2.2 and PHP 5.2.11.11.

If I export a vCard from Outlook 2007 (save it on my local computer) then try and upload and import this into roundcube it starts 'Importing, Please Wait' but after 4-5 seconds goes to 'This web page is not available.' (failing with: https:///webmail/?_task=addressbook&_action=import)

I have checked the Apache logs and the roundcube logs can caanot see anything that helps.

Anyone have any thoughts\ideas?

Thank you in advance for any help,

Dave.
