Thank you for your help but,

I downloaded but in stimulsoft's page it is written; For installing the build you should copy all files to Program Files\Stimulsoft Report.Net 2008.2 \.Net 2.0\Demo\Bin\.

My stimulsoft.net is a trial and I don't have this folder , instead I have C:\Program Files\Stimulsoft Reports.Net 2008.2 Trial inside this folder I have bin, docs,install, quickstart and samples folders. There is no demo folder or .net folder in stimulsoft. I copied new downloaded files into C:\Program Files\Stimulsoft Reports.Net 2008.2 Trial\bin directory.It overwrite some files. Nothing changed. The same bug exists. What can I do?

Hello,

Also you need update copied files in GAC. You can do this with help of Control Panel:

Control Panel->Administrative Tools->Microsoft .Net 2.0 Framework Configuration->Manage the Assembly Cache->View List of Assemblies in the Assembly Cache

Thank you.
