Activating the PRT designer from the mainmenu will result in a script error. Afterwards it opens with normal(?) funtionality.

The PRT Maker and the script have been totally overhauled for the next build.
There will be no more errors on start up and the effects will be significantly easier to control, I promise:

In the future, PLEASE post the actual error message from the MAXScript Listener.
Screenshots of the UI rarely help to understand where the error was.
Sorry, i already grabed it but forgot to send.
cheers
