Excel 2010 in Aspose.Cells 5.3.x and 5.2.x


I hope someone can help me. We are able to use aspose 5.2.x and 5.3.x to open xlsx files from 2007 Excel. However, when we try to open 2010 Excel files, we get "
Error Description: Exception of type 'System.Web.HttpUnhandledException' was thrown. Object reference not set to an instance of an object. at ..."

The exception looks like this:

ڍ..ↇ(XmlTextReader ) at ڍ..(XmlTextReader ) at ڍ..() at ڍ..() at Aspose.Cells.Workbook.ԝ(Stream Ԡ, LoadOptions ԟ) at Aspose.Cells.Workbook.ԝ(String Ԟ, LoadOptions ԟ) at

Anyone have trouble opening Excel 2010 files? Does aspose support this version of Excel?
