Sorry about that. Our email system is down, but we can help you out on our Discord.
If ISXEQ2 and Innerspace are new to you, we recommend starting either
on their pages, or visit our discord to find some extra context.
Long story short, you will need ISXEQ2 and Innerspace active and running to use ISXRI.
RI is usually intended for farm mode, i.e. when your group is comfortably geared for the instance -- if you need the gear from the zones it's best to run them manually.
