I have FB as well play FarmVille. I cannot receive message, nor send them, I cannot receive or send gifts and the chat area won't open up for us. It has been this way for about 3 days now

You will need to contact Facebook support for that.. Here is a link to their live chat:

Hi The farmville gifts only lasts for 24 Hrs. Before you get the gifts in gift box, you need to accept them in the facebook requests page. Also one can send a gift once in a 24 Hrs time. The face book requests can be found on the right top in the Facebook home page.

could be a sync problem with your FB account, you may want to email FB (facebook) about it so they can look into this for you.

My farm vile is not working and i went on www.farmvile.com and the same problem is accering the load bar is stoping around half way what eles could i do to get on my farmvile ?

That's not quite the problem, I think (I have the same)
I have now four neighbours which come up in my list as "Neighbours" but they have a blank "?" picture and no name. I can see their rank, XP and coins, and I suppose I can send gifts.
But I cannot remove them as neighbours!!! They are unproductive neighbours for me and vice versa but the "remove as neighbour" link does not work.
