Contacts grayed out when syncing...why?

[mxcnvida#AC]

I'm a new user coming over from the BB Bold. When I try to sync my contacts with HTC Sync, the area is grayed out and wont allow me to sync and backup my contacts. Is this because I don't have Outlook or Outlook Express? I have Windows 7 Premium, and an HTC Aria (FYI).

Any help would be greatly appreciated, and thank you in advance
