Aras 10.00 cannot create or edit anything

Hello,

I've succesfully tested Innovator 9.4. As soon as I saw rel. 10 I uninstalled ver 9.4 and made a clean install of ver 10

New release is very, very nice, but I could not edit any item and, when trying to create a new user I got messages like 'the login name is required'. Of course I did enter a login name. I was logged as root and also tried with admin.

So I tried with other item types, like variables, configurations, etc, but still get the same type of error messages.

I installed Aras on windows 7 ultimate with SQL 2008 R2 express.
