I wish you had mentioned .NET 3.5 sooner, in my investigation of this report I was using .NET 4, possibly there is a problem with the Form Wizard Package for .NET 3.5, I will look into that, possibly a file was left out of the compilation.
However for many reasons including that we may drop support for .NET 3.5 in the not too distant future, I highly recommend update your installation to .NET 4 and the .NET 4 packages of mojoPortal and add on products such as Form Wizard Pro. We have very few people still using .NET 3.5, .NET 4 is much better and .NET 4.5 is now out. In fact I recommend use .NET 4.5 hosting and the mojoPortal packages for .NET 4 for best results. At some point we will make .NET 4.5 packages but that is when we will drop 3.5 support. However .NET 4 apps run just fine under .NET 4.5.
Best,
Joe
