Hello!
I have the same problem.
I also tried with native OpenXML -> SpreadsheetDocument.Open method (Stream, Boolean) see http://msdn.microsoft.com/en-us/library/office/documentformat.openxml.packaging.spreadsheetdocument.open.aspx (open excel file from file or stream), but problem stil exists.
So, in anyone found solution, please write post here.
best regards
Grzegorz Pawluch
