Hello, I recently upgraded to gold member. I was taking the online D.O.E. C.O.R.E. test last nite with no problems. This morning I get to the window that says to take the test and when I click on the take test button I get a blank black screen every time. What is the problem and can you see if it can be fixed? I really need to use the tests as I have a real test to take Monday and I could sure use the practice! Thank you, Kp
