Installation failed: Invalid Key

Hi there!
I have a RB133 which didn’t survive a storm.
So I tried to connect to it via RS232 and luckily I got to see the RB boot menu, and I set it to Ethernet.
I ran Mikrotik Router Installer and saw the RB properly, but when I tried to reinstall RouterOS I get this message on RS232 Terminal:
Welcome to MikroTik Router Software remote installation
Press Ctrl-Alt-Delete to abort

mac-address: 00:0C:42:16:53:5F

Waiting for installation server…

And in Mikrotik Router Installer I get the message: “Installation failed: Invalid Key”

It seems that key was lost due to the storm…

Can I save this routerboard?
Do I have to pay for a new license??? I know there should be a way to fix this… Is it?

Thanks you all in advance!

All RouterBOARD keys are in the http://www.mikrotik.com account system. Just log in, copy the key, and paste into the router.

Thank you Normis!
I entered to mikrotik site, and found there the keys I’ve bought for my PCs, but I don’t know how to find the ones I purchased with routerboards…
Do I have anywhere to search using Mac Address or soft-id ?

I’ve never registered the routerboards I bought to local dealers, do I have to?
Where?

if you bought from dealers, use “Request Key” link in the account, you will be able to search by SoftID

Thank you Normis!
