So, I decide one day to download the instruments addon created by Elektrik, and once I downloaded it and put it in the Blockland folder and tried to start a game, it just came up with a runtime error. And yes, I unzipped the Instruments folder. Also, I removed the addons (the instruments addon has 2 files: Support_Instruments and Instruments) and it worked. So, if you know how to fix this, please reply to this thread. Thank you.
