Premire pro singing in issues

Hi, anyone know how I can fix my premire pro.Whenever I click on premire it opens a window showing the sign in page for adobe with it loading.But then the window closes and then opens another window and it repeats with it closing and opening another.Can anyone help ? I have no idea what is happening with my premie pro.I deleted the premiere installer and tried to re download it but it doesn't work and comes up with a quick message about firewalls and stuff.I have a deadline due in like 3 weeks and I need my edit done.If anyone can help thanks.
