Not fishing for anything proprietary but someone suggested that after deleting said file that decoding of P25 Trunked calls worked like a charm. I deleted mine and it started working also. Given that, I wonder if deletion of that file on a routine basis at start-up time has any unintended consequences that I may not be aware of. Also, if this is a known issue (who knows - maybe coincidence that it just started working after deletion) is it possible to include deletion of that file as part of the *.exe start-up process at the code level instead of through my batch file process(s)?
