I installed 8.14.01 today and the program cannot open. I am using the bin64 version. The launcher checks the license and then disappears. If I try to relaunch, it gives the multi-instance error. The platform does that often because the NinjaTrader.exe process sometimes lingers after a crash, but this part is easy to fix by killing the process and then relaunch. No more multi-instance error but the program again does not open.
I tried repeatedly all the routine fixes and none help. I reinstalled as repair; I removed the program entirely and reinstalled; I rebooted the machine. Nothing helps. The problem persists now in the older version 8.13.0.1 too. So I cannot even go back to a working version.
Please help
Thanks
