To log into your account, you need to enter the login/username you have selected during your registration and the password in the correct fields. You also need to enable cookie files.
The most common reasons for a failed login attempt are as follows:
1. You have used a wrong login/username and/or password. If you forgot your password, use the "Remind password/login" link.
Remember that the system is case-sensitive so pay attention to lower and upper case letters.
2. You have used a wrong login/username. If you forgot your login, try to find it in the beginning of an e-mail sent from the system, or use the "Remind password/login" link.
If this option does not work, please contact us.
3. The Cookies option is disabled in your browser.
4. Your user account is inactive - perhaps you have forgotten to activate it. It is not enough to register in the system. You also need to activate your account by clicking the link sent in an e-mail "Registration Step 2 of 2".
5. Your company network settings prevent you from using our system. This can be caused by limitations in your browser or your local network security settings.
If this is the case, try changing your security level or log into the system from another computer. You should preferably contact your network administrator.

Check if the activation link is complete. It may be "broken" into two lines.
To work correctly, the entire text of the activation link should be fitted into one line.
