Datamaster problems

1994 LT1 - this is the error message I'm getting.

AnalyzeMessage: status = 1, Unknown data present
The ALDL adapter is working, and unknown data was detected.
This may be an unsupported PCM type.

Do you have the correct version of DataMaster for a 94 F-Body? What type interface cable are you using? Are you using a USB "adapter"?
