Using Office 2010 when I insert an Excel worksheet from file into PowerPoint, the worksheet will appear but when I double click on it I get the following error message: “The server application, source file, or item can't be found, or returned an unknown error. You may need to reinstall the server application”.

Also I can insert a blank worksheet, but when I double click on it the screen goes a little crazy for a second or two – like it is refreshing or something?

Any ideas on what to do?

Thanks!!
