I took the PMP test at Prometric a few weeks ago, during the test, the system locked up with several of the questions that had earlier were reappearing.  Hourglass appeared for several minutes.  Failed the test in all 5 groups.  Contacted PMI regarding the test issue, they yet have gotten back to me regarding this issue.  Not trying to be "sour grapes" but felt that the results were skewed.  Has anyone else gone through this?  Thanks!
