I had this issue, but for me it was an 8008 internet error first, I solved this by applying minime v16 Hotfix instead of v16 itself and it fixed the issue for me. At the same time, I also went into app>package>DEVICE and made a txt file called aime.txt and put down 20 random numbers. (Dunno if this step is needed) and that fixed it for me.
Also when you boot up the game via Teknoparrot, make sure animeme's start.bat is running at the same time; without it, the game will be registered as offline. So run start.bat, then go start the game via Teknoparrot.
