I tried to log in but this message appears: " There was an error with your email/password combination", then I tried to reset my password and this is what appears:" An error has occurred. Please clear your browser's cache and try again."

I send an email to support but didn't get any response.

Deni, as far as I know, you should have received a reply from a support agent. Please check your email including spam/junk folders.
