Flexgrid Export to Excel errors out as row count exceeds 65,000

Hi All,

While exporting data from flex grid to excel using MyC1FlexGrid.SaveExcel("C:\MyC1Data.xlsx","sheet1″,C1.Win.C1FlexGrid.FileFlags.IncludeFixedCells) method we are getting argument exception saying "Maximum number of rows exceeded (256,65)". We are using 4.6.20111.602 license version of flex, windows 7 OS.

Any help regarding this will be appreciated..

Thanks
