Adding your post to the immigration practice area....
You will need to consult with an immigration attorney if you want to reactivate your petition.

It appears as though you were contacted by the NVC to start processing on an approved I-130 on Feb. 4, 2012 and one year has passed with no activity, so they are cancelling the petition. If you received invoices last year and never paid or took action, this is why it is happening. If you never received invoices or anything and suddenly got this in the mail, then it is likely you could demonstrate that the failure was due to circumstances beyond your control. As they indicate, you have one year to establish the failure was beyond your control and get the petition/application reinstated and proceed with NVC processing.
If you are uncertain as to how to go about this or have ANY hesitations at all, it is in your interest to consult with/retain an immigration attorney's help so you get advice you can rely on and some peace of mind in your case for your husband. Good luck to you and your husband and start taking action now!
