Here's a update. Dark Avatar is behaving correctly.
I went through and re registered my old GC2 and GC2DA serials as it prompted me to... (why?) So i used the new impulse serial.
Upon returning to the TOA game now, the 2nd core works.
I have no idea what could have caused this. Something is definitely fishy with TOA. Apparently launching Dark Avatar before TOA did it,
(as I re-registered TOA after it worked...)
So its either...
A) Dark Avatar must be launched once before TOA.

Somehow the activation mechanism for TOA checks DA (???)
C) I have no idea.
Something is buggy somewhere. I'll keep you posted.
Oh yes and TOA cannot ALT-TAB without crashing. This is both verisons 1.91 and 1.92a. Please fix this....
