Just tried playing again without my custom race and custom tech tree and it worked fine.

So the serial number wasn't the problem.  It must be my tech tree, I'll edit this reply later to include my custom tech tree and all things tied to it.

*WARNING: Wall of text and code ahead.*

Can you guys find what causes the error in all of this code please, 'cause I can't find it.

Here are my custom techs:

Sorry for all the text and code.                                                           

If you need the full file(s) to find the error just ask me for them.

All of my custom techs are at the bottom of the tech tree.

I used the editors that came with TOA so the order they are in should be fine.

Solved the problem, apparently I deleted a tech in the tech tree that was needed by the game.
