The file SampleListinterface.txt could not be opened

Hi
We are using Empower 3 connected to UPLC PDA with 3100 mass detector. The system is previously configured with QDa detector.
We are getting following error message:
The file SampleListinterface.txt could not be opened. Check the file exists and is not read only.
Please suggest.
best regards,
Praveen
