@alexthill hi there next time please follow this and post your game version, game launcher, and provide your logs at .minecraft/logs named latest.log

Yes, they are premium servers. (Sorry for taking a while to answer.)

@vlado your EMC is outdated. Delete libraries/me from .minecraft and restart.

how did you fixit because i have am having the same problem

@creeperguy350 Try following this guide https://discuss.aristois.net/topic/13/how-to-uninstall-optifine-optifine-error-on-startup

@armanis do .say .
Example: .say .help it will show as .help in global chat

@dyiing Ok

Yeah this is not related to Aristois. The Auth servers are down or something else, so you need to wait.

@ehylo You are the GOAT! Thanks!!

@_sekku The official launcher logs don’t look like that, unless you’re using legacy, which still is not supported.

You can try manually downloading the files and placing them in the right place instead.

@vnx043 see my response here

You can probably reinstall Aristois to reset the addons. If you're comfortable with deleting files you would want to delete:

C:\Users\ [Your Username ] \AppData\Roaming.minecraft\libraries\EMC\ [Client Version] \configs\Aristois_config.json

and then start the client again.

It should reset your addons to default.

@nightknight .t tabui

@piedelemon Follow this guide https://discuss.aristois.net/topic/23/invalid_checksum-error , if the issue persists please send the crash report.

It's working now. Joined a single player world then joined a server.

@hiineedhelp What?

@skeetuser Delete the libraries/me folder in your minecraft directory to fix it.

@greedytwo Works fine on my end, not a bug in Aristois. Not sure why it's not working for you.

@lixrd This has been fixed, and will be released in an update very soon.
