I had a problem which when i upgraded the tools to the lastest version which do not require any dongle. It seems like i can't login to the server using my email fo the verification. I bought the dongle from a reseller which i suppose he had used it first and used his own email registered to the dongle. The problem is the reseller wont tell me his email associated to that dongle's serial number. I wonder if i can possibly change the email related to the serial number i am using
