Configuration File Corrupt

Recently, when i tried to open my BizTalk Adminconsole it got the following errormessage:

root element is missing (c:\Documents and Settings\UserName\Local Settings\Application Data\Microsoft Corporation\Microsoft BizTalk Server 2006\Microsoft.BizTalk.Administration.Snapin.dll.config)".

To solve this error, just delete the Microsoft.BizTalk.Administration.Snapin.dll.config file.
Next time the Adminconsole will recreate this configfile :)
