Employee Card will not open in RTC

I have a situation where we have setup user with certain roles with permission to read, modify, insert, delete the employee table and run permissions on all pages, tables, forms… When the user opens up RTC and accesses the employee list and tries to edit or view an employee card the card doesn’t come up. No error messages. Nothing happens. They can’t event create a new employee. Any suggestions would be helpful. Thank you.

Try to synchronize the user logins

Yes I have synchronized the user logins.
