Hopefully you still have you NVC case number.
1. Try to log into the NVC website to check the status of your case
(Most likely your case will be closed).
2. If closed, send an online inquiry to NVC to see if you can renew or reactivate your case. Try to be clear and succinct in your request.
(Most likely your I-130 will have been considered abandoned and you may be asked to refile. Or you may get lucky and be allowed to reactivate your application and thereby avoid the fees.)
3. If all the above fails, then you will have no choice but to refile and pay the fees again assuming your husband still wants to join you in the US.
4. Whatever the outcome, you will probably need a complete set of update to date documents from you and your husband, including communications, evidence of travel, etc to show you are still in a bone fide marriage.
Wish you the best.
