It sounds like you got a restricted license pursuant to a DLAD appeal and you now have the interlock for 12 months. If you blew a positive result, that is considered a major violation and it is going to be a problem and you are going to be called in for a hearing.
The best thing you can do at this point is hire a criminal defense attorney to consult with you regarding possible mitigation/damage control.
If you have an alcohol interlock for some other reason, I would need to have more details before I could tell you what to do. You can find a 10.0 rated criminal defense attorney by searching on Avvo.
