Hey, Inestea. That means RLC has blocked your IP address from accessing their site. You will need to change your IP in order to regain access. I know of two ways of doing that. There may be others.
If your ISP serves up dynamic, not static, IP addresses, you can sometimes change it by turning off your router and turning it back on. How long you have to leave it off is anyone's guess. It may be five minutes, overnight, 24 hours, etc.
When you reboot your system, if your IP is always the same, then your ISP assigns static IP addresses and the above probably won't work. To find out, just Google, "my ip" without the quotes, before and after you restart your system. If they're the same, they are most likely static.
The other is to use a VPN. The problem there is, RLC blocks a lot of the IP addresses used by a lot of the VPNs. It's just hit or miss until you find one that works. There are free and paid VPN services out there.
I hope that helps.
