What OS are you using?

It should be fine on Windows 7 x64... I haven't seen the error but it looks like there are some non SmartCoin related instances on the web.

I would look into this one: http://www.sevenforums.com/gaming/313426-ntdll-dll-game-crash.html
The causes of ntdll.dll error messages can vary greatly. However, most ntdll.dll errors result from a corrupt or damaged version of the ntdll.dll file itself, corrupt hardware drivers, or issues between Windows and other programs. Ntdll.dll errors can sometimes mean that a piece of hardware in your computer is malfunctioning, but this is rare.
I decided to move the wallet to another PC to eliminate any corrupt file related issues. The wallet still crashes, similar event log entry as before but this time the wallet file itself
