## Q&A

***Q: Where do I get and how do I input the code required to play Lilypad QA?***

Please do not email listed on the input screen in Minecraft, use the exalpha-dev website instead.
**A**: Go to https://exalpha-dev.github.io/g\_registration.html, and enter the username you’re using into the text box and press the “Generate Key” button. The key should be copied to your clipboard now. Paste the key you got into the input box and press the “Input” button.

***Q: I get the `NOT THIS TIME TIMOTHY` error***

**A**: Set the JVM argument `-Djava.util.Arrays.useLegacyMergeSort=true`

***Q: I get the `Unable to authenticate using ULPP` error***

A: Try re-logging in a few hours as this usually means that Mojang's authentication servers are currently down
