The demo is broken

I got a recomendation to try this out by a freind (and hopefully buy it afterwards) so i downloaded the demo.
I got this message in debug.log:
DSQ init
Mipmaps Enabled
DeveloperKeys Disabled
VoiceOvers Enabled
Init Graphics Library...
I read another thread were you've fixed this error, however it seems that the demo is a bit old

2.4 ghz Intel Core 2 Duo
2 gb ram
Nvidia 8600 GT
(Macbook Pro 2.4 ghz, currently in bootcamp).
Yeah, please fix this, my freind totally freaked out over me not having played it yet. It seems to be a great game. However i am a hard time osxuser, i don't know how you handle the copy protection, but i read that ambrosia software will do it. I believe they have their own copy protection. However, i hoped that you could fix so the same serial or whatever system you use work on both systems. So if i buy it to PC i would be able to play on Mac. It would be a shame otherwise. It is after all SDL based so it shall not be a single problem porting it if you aren't using windowsspecific API's and headers.
However, please fix the demo or give me a patch to the demo here. Thanks for being unique and making great indie games that people enjoy!
