Hello Jim and Seth, Thank you for your support. The service test scripts all run fine. My own scripts persist in the error given above. My own service loads but aborts at import serial, which, I guess, has not so much to do with serial, as with something else. I will try and upload the relevant data and errors. Keep you posted. Thanks again (it getting very annoying though....), cheers, Harke
