Dotfuscator 1.2

Just downloaded the latest edition of Dotfuscator Community Edition
1.2. When I run it on my assembly, I get the following error message:

Saving Options...

Running c:\Program Files\Microsoft Visual Studio .NET
2003\SDK\v1.1\\bin\ildasm.exe

Settings\Michael\My Documents\Visual Studio
Projects\Calendar\bin\Release\Calendar.exe"
The data at the root level is invalid. Line 1, position 1.
Build Error.

The project is a pure C#. Any ideas?
