Also, have you tried reinstalling MEmu and the bot by the following steps?
1) Remove ClashFarmer from Program Files (x86), and reinstall it with "Run as administrator".
2) Uninstall Bluestacks/MEmu from windows (add/remove programs).
3) Reboot the PC.
4) Install Bluestacks/MEmu again and configure COC. You can find the download links in our FAQ,

5) Run the bot

This error occurs when you don't resize the screen on the new MeMu version. I just got it too. Resize your screen to the new settings and it works again. The thread said it's been fixed, but it hasn't.
