locked Subprocess error


I have finally got my transceiver and computer talking to one another and WSJTX seemed to be working alright. However, I got a number of errors.
" Running C:\WSJT\wsjtx\bin\user hardware 10 ( also 15,20 and 40).Process failed to start:The system cannot find the file specified."
What does this mean and how do I correct it?
Kind regards
