Well that makes me feel better as hopefully come monday, mine will be up and acting right again. I have never seen this before and am very nervous. I even tried to put in a "sell order" just to see what happens and under the "stock quote" on the right hand side (that shows you the bid and ask when you try to buy or sell) says "you have entered an invalid symbol, would you like to do a symbol search".
It's not very comforting at all to be honest but like I said, hopefully come monday, everything will be ok
