Quad Cortex login problems

Hi guys! I need help. I can’t login my QC. When I try to do this, I get this message. I wrote to tech support, they said to reset my QC. It did not help. They no longer respond to my messages. Please help me to solve the problem with the login.

When did you last communicate with support as they are they only ones who can resolve this issue with your account. Either your username or password is incorrect it seems, maybe they can reset your password.

I have the same issue and the resolution is to ship it back to Finland… which is very inconvenient since i come all the way from the philippines and their preferred shipping company has a very bad reputation here in our country… now im stuck with conversing with the support team
