Can’t obfuscate

I use VS2010 and installed the september release.

I add a new project to the solution, click RemObjects Oxfuscator, Add reference, choose my project.

Then build the project and get the following error:

Error 3 (MSB4028) The “PreapareObfuscarVars” task’s outputs could not be retrieved from the “FilesToObfuscate” parameter. Parameter “includeEscaped” cannot have zero length. C:\Program Files (x86)\MSBuild\RemObjects Software\RemObjects.Oxfuscator.targets 27 7 OxfuscatorProj2

The targets file has this:

< Target Name=“PreapareVars”>
< PreapareObfuscarVars OxfuscatorXMLfragment="$(Oxfuscator)">
< Output TaskParameter=“ObfuscarConfig” PropertyName=“ObfuscarConfig” />
< Output TaskParameter=“FilesToObfuscate” ItemName=“FilesToObfuscate” />
</ PreapareObfuscarVars>
</ Target>

If I try to go to the properties page, it shows the following message:

An error occurred trying to load the page. The path is not of a legal form.

Any ideas?
