Accenture India — Regarding coding round login issue

Today was my Accenture assesment test .I give the first round of cognitive assesment and cleared it and received mail for next coding round.But at the time of starting second coding round it was not getting loged in.Then I contacted support team assistant and by taking their advise I closed the window and download SEB browser again and when try to login again it was showing that "Test validity is over". I was not able to give the test further. Please look into this. I have worked had for this and because the issue I can't complete my test.Please solve this issue as soon as possible.
