Design Studio error after upgrading to BO 4.1

Hi,

We were using Design Studio version 1.1 without any problems and we recently upgraded our BO platform to version 4.1.

This gives us now Design Studio version 1.2 which we needed to solve some issues.

Unfortunately, our Design Studio is no longer working correctly. We always receive the following error message :

Error while calling method "DoSetTemplateCommand"

The initial exception that caused the request to fail was com/businessobjects/sdk/plugin/desktop/zen/boe/template/IZENTemplate

The error occurs for old applications and new application which prevents us from using Design Studio at the moment. We cannot find any information on SCN or OSS.

Does anyone have an idea ?

Thanks in advance.
