Can I somehow reinstall 3DGS? Recently, things have been really wacking out with WED and SED.
For example: The following is an attempted run of the techdemo. Since when is "camera.ambient" an unrecognized keyword?

I haven't updated yet, as I am afraid it will make it worse somehow. What can I do!? I can't do anything in SED or WED that remotely involves running. If I run a level that has no script attached, (I.E., a level with a single simple square) I get:

What does that mean!?! "In main:"? As in, the source code was altered?! Augh! Somebody, please help. And any other attempt to do something (E.X. Pressing "0" to scroll through level) prompts a new error.
Also, I have seemingly lost the ability to apply scripts to levels that I make that are new, as the button to choose script/new script are grayed out.

Basically, I can't
do anything. What is the problem? How can I fix it? And let me assure you, I am almost 100% positive that my version is legal.
