No. It stays on, Windows stays out of test mode, and there's no watermark on your desktop. Add an antivirus exclusion for the loader folder, or it gets quarantined halfway through installing.
No. If the loader closes the instant you open it, with no window at all, you're in a VM. That's the refusal, not a crash.
Your licence checks a set of machine identifiers, not one hash, so a new GPU, a new network card or a moved drive is fine and you keep playing. Replace the motherboard and the system disk together and it's a different machine, and it will be refused. If that happens to you for a legitimate reason, open a thread on the forum.
No. It locks to the first machine that signs in. Licences that move between people get revoked.
No. Press LAUNCH once and start the game whenever. Raids aren't separate processes, so it survives dying and extracting without being loaded again.
Assume it's broken until you hear otherwise. The loader refuses to run against offsets it hasn't checked, so you wait for a new build.
At our discretion, case by case. Ask on the forum with a reason and we'll look at it. A ban isn't one. A payment that went wrong usually is. The full policy is on the refund page.
The forum. Announcements and patch notes go there too.
