I just tried to run the NAudio demos and I'm getting a weird error:

System.BadImageFormatException: Could not load file or a
ssembly 'NAudio, Version=1.3.8.0, Culture=neutral, PublicKeyToken=null' or one o
f its dependencies. An attempt was made to load a program with an incorrect form

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\M
icrosoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure lo
gging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fus
ion!EnableLog].

Since the last time I used NAudio demos I have changed from 32bit Windows XP to 64bit Windows 7. Would this cause this issue? Its very annoying as I was about to try my hand at audio in C# again
