We have upgraded our Aspose.cells component to v4.4. (we also tried v4.3).
We are receiving an error when trying to load a file that's created with Aspose.cells. The error we recieve is "Index and count must refer to a location within the buffer. Parameter name: bytes".
After you open the file in Excel and Save it, it will load into our application without the above error.
The attached file is an example of an Excel file created by Aspose that Aspose cannot read back in.
