Supplier Log In

In addition to other problems that are still happening I am now unable to access my supplier details. When I enter my password etc, nothing happens. When I try to do it via Sign in, it takes me to a different log in and that doesn't recognise my password even though it's correct. I also haven't been able to use the email system on the forum for approx 2 months. I can't send emails,receive them or hold conversations with anyone. I thought if I could enter my email address on my signature,this would help until the problem is resolved with the email system but I find I can't access my supplier account now!
