Expertise on MS Dynamics beta would be greatly appreciated

Your expertise on MS Dynamics beta would be greatly appreciated. I am very new to this so please bear with me. I already installed this in my computer. When I installed the database, it said that I couldn't link with the server database. However, I could connect with R2 previously. I already tried the setting to permit the administrator, tried to create new servers, but all to no avail. What went wrong? What should I do?
