Happening on both Mac and PC version 9.10 issues with safe mode; Javascript

Hi, I am required to use version 9.10 RapidMiner for an educational program. I have attempted to use RapidMiner 9.10 on my Macbook and PC for a few months; however, I have experienced ongoing issues. The software will not start other than in safe mode on both the Mac and PC. On PC, Java could not be launched errorcode 1. I have removed and reinstalled 9.10 RapidMiner on both machines many times; however, the issues keep reoccurring. I have to remove and reinstall the software practically every time I attempt to use the software. This is happening on both Mac and PC. Any advice would be appreciated.
