The problem of signing the demo version of EFDC 10 and EFDC 8

when I use the registered account to sign in the demo version of EFDC 10, it always failed just like the picture below. Besides, when I sign in the demo version of EFDC 8, it always tells me my account does not exist.

The accounts used for EE8 are no longer valid. Can you login to the EEMS website with the email address you are using? If you can it should work using the same password you use for the website. If you cannot login then you should reset the password and then login. After that you can use the demo mode in EEMS11.2.
