Hello,
@purable.
You do
just need the VIP rank, however if you claimed your monthly reward(s) previously, you need to wait exactly 30 days before re-claiming them.
I believe the warning for that incident is different, though. I’d suggest making a support ticket if it’s still not letting you claim your rewards, but before you do just double check you’re spelling your username correctly, as it’s case-sensitive.
If you have already claimed your rewards previously, you can check how long ago you claimed them by typing “/gary”, clicking the keys and then clicking the link which says “see when you last claimed your rewards”.
