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.

@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.

@fatninjas It probably modifies something that Aristois also modifies which causes a conflict, there may or may not be a fix in the future depending on how hard it is to fix.

alr its actually fixed now and im beyond happy

@dyiing NVM IT WORKED. TYSM!!

@deftware Ah thank you, guess I wont be jumping lolz

@oxy As long as you use the alt manager to load the non-donor alt, it should not eject. I tested with my alt and it worked as intended.

You just need to start the game with the donor account logged into the launcher

@swoamazin If it won't show, I'd assume that you're on 1.12.2 or lower (or forge). The addons are fabric only, for 1.14+.

To get optifine on lower versions, you would need to use forge.

@ralledk I believe we were talking on email? I'll answer here anyways, so others can see.

Try using the command ".setbind gui".
If you get an error that says "could not find mod gui", this may mean you're trying to load the donor client with a non-donor account.
If it says "unknown command at position 0:" then Aristois isn't loaded, and you need to delete libraries/EMC, net, and me.
If it works correctly, but pressing the new key doesn't open the menu: If you are on 1.14, this is a bug with the gui. Use 1.14.1, 1.14.2, 1.14.3, or 1.14.4 instead.

If none of the above works or your issue is different, a staff member will need to take a look
