Linking Contacts to Facebook

[scraider58]

I've had my Incredible 2 since the week it came out. I promptly linked my contacts 1 by 1 to their Facebook accounts. However, last week one of my contacts got un-linked (yes, probably not a word) to their Facebook. This has happened before to people who deactivated their accounts, but this contact still has an active profile. When I try to link it again, it doesn't show him as a Facebook friend. Help?
