CreateProcess failing after license upgrade

[bsusi]

Hi, I'm a long time user of the tool, but my organization just renewed our DPlot license and I've now lost the ability to use the Excel add-in. I can open and use the full DPlot application without issue, but trapesing through the VBA code I find that "CreateProcess" in "DPlot_Start" is equal to zero and so the handle is never assigned and nothing happens. I've checked the other variables and the correct version of DPlot is found from the registry, and the location is correct, but something happens in CreateProcess and I'm not savvy enough to figure out what. I greatly appreciate any help!
