Weird error ...
How I got to this was ... missed / didn't click Continue upon opening AutoCAD and then MV. So got into AutoCAD ... type MVTB7 (like I've done before in the past) and this error comes up.
Double checking the NETLOADMVTB7.lsp it shows this:
(command "._NETLOAD" "C:\\Program Files\\Microvellum\\Toolbox\\Microvellum.Toolbox.dll")
Invoking this command at the prompt ... returns nil (becauae it did load???)
On build 25_2_0227_641 - Updated to latest build 25_2_0317_641 - SAME issues / error.
