I'm not in the office right now, I didn't expect an answer so fast, it said something like it's not valid or incorrect license. Thank you for your time

Hi, I bought a 5 License pack and used it in my 5 PCs with no problem, but after formatting 1 PC, i could not reactivate this PC, is there any way I can delete 1 License to reuse it? Or in other words, does eset have an "Admin Panel"?. I ONLY have one serial number valid for 5 PCS, i dont have an username and password. Thank you for your replies.
