You will find lots of samples here that illustrate how to use Solid Framework.
All of these samples will work with a Trial License, but the output will be mangled if a Trial License is used. This means that the reconstructed document will contain watermarking and deliberate substitution of some characters for others.
To see what the output would be like with a full license, please visit SimplyPDF.com. This provides online reconstruction of Word, Excel and PowerPoint documents from PDFs using the latest released version of Solid Framework.
