Ninjatrader 8 64bit won't open

[amandam239]

Hi. I went to open NinjaTrader 8 64bit this morning and it won't open. I saw on this forum someone had the same issue and a repair was suggested by customer support, so I tried it. This is what I did:

"Thank you for your post.

Generally, when NinjaTrader will not open, it is because some necessary system files have inadvertently been removed. This can either be by the user directly or by PC cleanup software. Before we proceed with a full uninstall/reinstall, let's perform a repair of the platform. To do this;

1. In the search box on the Windows taskbar, type Control Panel and select it from the results.
2. Select Programs > Programs and Features.
3. Locate NinjaTrader 8 on the list, right-click on it and select Repair, or if that’s not available, select Change. Then follow the directions on the screen.

After completing the steps above, launch NinjaTrader 8."


After I did the repair, a new ninjatrader icon appeared on my desktop but when I opened it, it is blank - like a brand new install of the software. My account is not there including my workspaces, etc. Not sure where to go from here.
