Evaluation Edition of dhtmlxScheduler for .NET version 3.5

I downloaded the the evaluation edition of dhtmlxScheduler for .NET version 3.5 at the following address,

s3.amazonaws.com/uploads.hipcha … 130912.zip

The dll gives the error, “Evaluation period has expired.” I downloaded the it one hour ago and download the version for .NET 4.0 two days ago.

Is there a link where I can get the correct evaluation version for .NET 3.5
