NinjaTrader won't open at all - get error message then it closes automatically

[EnveousColnago]

Been running NT8 with no problems, then today when I try and boot it up I get the attached error message: unhandled exception: '.', hexadecimal value 0x00, is an invalid character. Line 1, position 1

Whether I click OK or not, the entire program then just shuts down. I haven't made any changes, installed any new indicators, etc, and in fact NT was working fine earlier this morning. I've tried rebooting the computer several times, and it's still doing it.

EDIT: I just tried reinstalling by downloading from https://ninjatrader.com/PlatformDirect and installing. Still the same error. I also won't be able to send any log & trace files since the program won't open at all to begin with. Please help!

Hello EnveousColnago,

Thank you for your post.

Glad to assist. To resolve this, shut down NinjaTrader if possible. Next, go to the Documents\NinjaTrader 8\log folder.

Next, delete 'Install.XML' file within the Documents\NinjaTrader 8\log folder > restart.

Please let us know if we may assist further.
