Ip Restrict

Hi, my IP address was restricted.

That ok, but i cant remove, when i login with ADMIN account, and try remove, i receive message success, but, when i reload page, surprise?!?!, he is there again.

In help zoho FAQ i find this.

If you don't know the IP address you've configured for your Zoho account, please contact Zoho Accounts Support .

But, i never received any anwser from them.

Could someone help? I know the error was mine to set a restricted ip, but unfortunately my router changed the ip.
