NinjaTrader 7 crashes on startup

[Yaron]

Hi,

I have the latest version of NT7 installed (licensed). When I launch it it crashes with a stack-overflow bug in both the 64bit and 32bit versions. I have shut down my PC, tried again, same result.

I have uninstalled NT7, restarted my PC, deleted the NT7 folder (program files(x86)\NinjaTrader), downloaded and installed the latest version, same result.

This is the message I get from Windows:
Description:

NT7 worked great for more than 40 days, it suddenly broke down.

Please Help.

Thanks,
Yaron

Problem resolved by deleting my workspace XML file located at "C:\Users\....\Documents\NinjaTrader 7\workspaces". Apparently, it became corrupt for some unexplained reason.

It is recommended to backup your workspace file from time to time (just copy it to a different location on your Hard drive or follow the NT7 help file section that explains how to create an entire backup here). Since I didn't do that, I had to rebuild my workspace from scratch... :|

Thank you Jason for your help.
