At first, I couldn't find the sql query designer tool, so I added it to the existing toolbar. My problem is that I can't use it, because it's grayed out. The problem may be with permissions (but I doubt it). Here's how I'm connecting: I connect to a database, choose my local machine's database, I click use windows authentication, and attach a database file. It seems to be the only way that works, and I cannot log in through the admin account because it won't let me attach a db file.
