Problem with nero vision express

When ever I try to burn movie files to a dvd i get this error

ERROR
[19:28:32] DVDEngine cause: 129 (neroapi_call_failed)
[19:28:32] DVDEngine source: NeroBAOOpenFile() returned error condition
[19:28:32] DVDEngine description: _BAOContext::OpenFile()

Any ideas, worked fine until last week or so. I reformatted my whole comp and reinstalled and this is what I get.
