Dana, We know you had WDM_Phasar from an earlier version of OptiBPM. Are you trying to run that by just copying the old WDM_Phasar directory to another computer? That won’t work. I have tried going to our website, downloading WDM_Phasar, and installing it. It runs all my projects and computers so far. We have not reproduced your problem here at Optiwave yet.
