Hi,

It seems that you used .Net 2.0 before and you upgraded with .Net 3.5 DLL files. Also, it seems that you added the assemblies to GAC before and now the version is not matching, so you need to update the GAC assemblies and also you can try to clear .Net cache (c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\).

Paid version is supported because part of the price is also support maintenance subscription as for any other product. Open source products have bigger communities, that is true, but if you want to have official support, it is very expensive (e.g. 100USD pre incident).

Best Regards,
Juraj Ondrus
