Did you adjust the reference values? Check the lift and drag force too. It's very common to not get the area correct so the force is OK but the coefficient isn't.  There are a few NACA airfoil examples/tutorials in the Fluent Help, they should explain what's needed. 

As an aside, staff are not permitted to open/download files and attachments. It's to keep us out of trouble with Legal (export compliance laws) and IT.
