Hi, I keep getting this identical error message each time I join servers. I didn't get this yesterday, and I don't know a fix. Any help?

420720weedlol make sure you launch plutonium via plutonium.exe. you may have the launcher itself (plutonium-launcher-win32.exe) pinned to your start menu, you won't receive any updates starting it like that.
