"crease" is keyword in 4.0 files that refers to the new feature supporting crease angles. It looks like ac_to_gl doesn't like seeing keywords it doesn't recognize in the AC3D file format, and is choking on this one. I'm assuming this tool will eventually be upgraded to support version 4.0? You may need to contact the author to make this happen.

In the meantime, if you're experienced in C/C++, you could edit your copy of the ac_to_gl source file to include the "crease" keyword.

Barring that, a hack-ish way to do it would be to make a copy of the .ac file from version 4.0 in a text editor and remove any lines from the AC3D file that begin with "crease" before running ac_to_gl on it.

I definitely wouldn't recommend this as a permanent solution, but it'll allow you to continue using 4.0. You won't be able to take advantage of the crease feature in any models you export (and it's a very nifty feature), and it's just a general pain to do this for every model, anyway. But it would be worth a try at the very least to see if it works for you until the ac_to_gl utility is upgraded.
