Fixed it!It'e either the firewall or Windows is preventing Sketchup to write files to /User/Documents/Octane/ folder. All temp and livedb textures are stored there. Please check if those folders are empty and report back to me, I'll try to figure out what's wrong.
The problem seems to be that if cannot change the default target location of the /User/Documents folder, I had changed my target to d:\documents. It seems that the plugin does not recognise this.
Hope that made some sense.
cheers,
