The game requires a product key. Why is this suddenly needed and how should I find it?

Hello! I am a huge admirer of this game, but every time I try to edit anything in my game when it starts. The game will crash, telling me it created a 'MLCrashDump10.dmp' in my documents folder and was supposed to let the team know about this issue.

Read the save and exit the game directly. What is the reason?

basically, everything happened as intended BESIDES the great war starting. I beefed up Sweden, took over norway, min maxed what i could, stacked everything without cheats or mods for at least 100 turns. and...... nothing happened. I wanted to help out finland and establish a sweet buffer state between the my swedish empire, figured id try to do that without the war happening and nope, russia destroyed me cause no revolution started and no war started :( are there any indications the war will start as i...

Okay, the british allies basically declared war on me (china) and so far I am kicking their ass, the problem is, now my native populace is having this nationalist ♥♥♥♥ going on and I can't seem to get em to stop. I mean I am WINNING, what more could nationalists want?...
