We have been working with your issue and have already fixed initial MD5 error. However we have faced a new problem with your sample file and unfortunately it cannot be opened in the upcoming .Net 2.4 release. We will work hard this month to make it ready till the next 2.5 release. Thank you for your understanding.
There is no ETA available for release of Aspose.Note for .NET 2.5.0. We’ll update you here as soon as some information is available to us in this regard.
