Aspose Excel v1.8.1.0 problem

hello
i am using Aspose.Excel v1.8.1.0 and have some problem with specific .xls files. There is a state list in my .xls file located horizontally - one state name in a column cell - and i think that this cause a problem in Aspose.Open method . i am not sure this is the cause for the problem but when i delete two cells from state cells, Aspose component successfully process it but when i delete just one cell it will fail again. it is difficult to determine what is wrong with .xls file.
Need help to determine the problem about this document.
