List of problems and how to fix them

Foggy

Here's a list of ways to fix current (usually rare) errors:

Zeroday crashes when I launch it (ERROR CODE 1): Inside the launcher, click the settings icon and slide down the slider a little bit (that's all you have to do). This decreases the allocated RAM, which can lead to FPS lag spikes. If you want to allocate more than 2 GBs of RAM, please download 64-bit Java.
Whitelist error: double-check that your system clock is set correctly, make sure to set it to automatic
Game crashes when you join a server (Fixed in b20): goto the baritone folder located at C:\Users\YOU\intentlauncher\baritone and make a text file called settings.txt and keep it empty. If you already have this folder, delete it and make an empty one.
EXCEPTION_ACCESS_VIOLATION (Should be fixed): Just press launch again.
Nothing happens when I run the launcher: Most likely due to outdated graphics drivers, https://www.drivereasy.com/knowledge/error-org-lwjgl-lwjglexception-pixel-format-not-accelerated/

If any new errors start happening or Nef patches these ones, I will keep this post up to date.

And just because, I'll put the rarity of each in this reply:

Whitelist error: Common, you wouldn't believe how many people don't have their clocks set correctly.
Launcher doesn't run: VERY rare, only happened to one or two people in the history of ZeroDay, and it's lwjgl's (A professionally coded library that Minecraft uses) fault.
ZeroDay crash: Common, lots of people don't have 64-bit Java
EXCEPTION_ACCESS_VIOLATION: Happens to everyone, all you need to do is press launch again. Soon to be fixed by Nef, most likely will be fixed by b20
Game crashes when you join a server: Uncommon, I'm not sure why it happens but it sure it easy to fix. Fixed in b20

but still good to do so you have a version of Java that is verified to be working
