Microsoft outlook problem extracting contacts

Hi there,
I have recently upgraded my Dell Inspiron PC from Windows 7 to Windows 8 and since then I have been facing several issues with Microsoft Outlook, I had backed up my contacts as a Vcard and extraction to outlook is starting from a particular Letter (N) the other ones are missing yet on my Smartphone I can extract all of them, secondly, inserting area code is troubling, how do I get to extract my contacts and change default Area code?
