Hi Stromausfall,

Yeah when I run the lite-c scripts that come with the engine it displays my name and lists it as Commercial edition. I have full admin privileges on my machine and the project is located in a separate partition to the OS so there shouldn't be any locks on the working dir.

I'm going to try and uninstall everything to do with 3DGS and then reinstall it all, I'll see if that has any bearing on the problem.

it's a confusing one.
