Actually i see this error during the instalation, in the 2. Database step. The error is exactly the same as the guy above commented. The curious thing is that I can connect to the MySql Instance through MySql Workbench. You can test it using the following data: Hostname: XXX User: XXX Password: XXX Database: XXX However, when I try to install revive-adserver using the info above, I got the error. Thanks, Marcio
