We have further investigated the issue on our end and our development team has not been able to reproduce the issue by using Aspose.Slides for Reporting Services 4.3.0. In fact, earlier by mistake I verified your RDL files with Aspose. Slides for Reporting Services 4.2.0 in SQL Server 2008 SP2 environment. But now our development team has verified the successful RDL export using Aspose.Slides for Reporting Services 4.3.0 in SQL Server 2008 R2, SQL Server 2008 SP1 and SQL Server 2008 SP2. I have also been able to verify thee same in above mentioned versions except SQL Server 200 SP1. Can you please share, which version of SQL Server you are using. Please also verify that if you are using the correct version of Aspose.Slides as mentioned above. For your convenience, I have also attached the generated presentations.
We are sorry for your inconvenience,
