Crashes and Corruption

[ramckay]

I've had a repeating problem of NT crashing and when it is restarted the Control Center window is empty - only File Tools Help [+/-] appear at the top of the window. In the past I've reinstalled NT and .Net 2.0. Sometimes it works and sometimes it doesn't. I just had the same problem so I reistalled NT. Same blank window on startup. This time I tried a system recover to yesterday and the new installation of NT started correctly. I had saved the old NT file (in my documents) so I renamed the new installation to Ninja Trader 6.5 New and renamed the previously bad installation to Ninja Trader 6.5 and the bad installation started up corrupted ( blank window). What is actually corrupted - an .exe file or one of the support files? The system recover changed something to allow the new installation to work. If I can determine what gets corrupted I can reinstall NT, replace the corrupted file with a new one and continue without needing to go through all of the setup process.
