NinjaTrader application has stopped working

[algotrade]

I have some problem related to the NinjaTrader database, and the application is exiting.
I have tried everything:
. Remove Documents/NinjaTrader/Application.XML, uninstall application and reinstall;
. Remove Documents/NinjaTrader/workspaces/_Workspaces.XML, uninstall application and reinstall;
. Remove Documents/NinjaTrader/db/NinjaTrader.sdf, uninstall application and reinstall;
. Remove Documents/NinjaTrader, uninstall application and reinstall;

The first time I run the application after reinstall it works fine, but after restarting the computer... got the same problem over and over again.

Does anybody have a clue on what could be going wrong?
Thank you
