A couple of questions for you. You obviously can post a new thread. Can you go back and view it? What is the exact error message that you get? Do you have any other tabs open?
Usually a database error is from the outside database, which, in this case, would be TCS. But I am not having any problems with it.
So, just to be sure, I would shut off you computer and restart it. Only go to TCS on the web (it's okay to leave other things like iTunes of Office open). But, definitely not a database program. Just make sure that only one internet site is open.
You can PM me with more questions.
