Time-Warner Navigator software deleted everything on my DVR Expander

Time-Warner Cable of Syracuse recently upgraded to the Navigator software system. For a day or two after I had all my recordings, then all of a sudden they disappeared…  going from 30% full to 3% full (shows recorded on the DVR before I installed the Expander remained ,)  I had all kinds of good stuff recorded. Is there any way to retrieve the recordings or are the gone permanently. Very frustrating and no real good prior notice from Time-Warner .

Thanks.

I’m sorry to hear that… What kind of DVR expander do you have?
