Hi Melissa,
Sorry that you had difficulties with your online test. I had difficulties as well the first time around. Your best bet is to contact Pearson Vue and have them start an investigation as well as provide you a case number. You should communicate this case number to PMI as well to help expedite the investigation. The first time I wrote the exam it crashed 20 questions in - I had gone through the system check and submitting photos of my work station and a proctor had launched my exam. Your situation seems specific, so I'm not sure anybody else on the forum will be able to provide much more for details.
Best of luck, hoping you get this resolved quickly! My case was resolved in 7 business days - you can stay sharp by redoing PrepCast questions, or re-reading your notes.
Kyle
