I get a IOException with message "block[ 0 ] already removed" while loading an .xls file. Demonstration code and file is attached in a solution that should run right out of the box. It should be very easy for anyone to reproduce. This .xls file loads successfully in Excel 2003 and 2007. The origin of the file is noted in Program.cs in the demostration code. I'm using the NPOI 2.1.3.1 from Nuget, but I also tried NPOI 2.2.0.0 and got the same results.
Building the demonstration code will automatically download the NPOI 2.1.3.1 package from Nuget.
I'll take any suggestions on next steps in troubleshooting this issue.
