export to bpel

just was trying to export an orchestration to an bpel-file which resulted in


the following error:

Error 1 An internal error occurred in the export component.


Additional Information: Object reference not set to an instance of an


object.;

I took a look around and found the article for the hotfix concerning biztalk


server 2004. (http://support.microsoft.com/?kbid=891045&SD=tech , hotfix


Microsoft.xlangs.bpel.bpeltranslator.dll). Does anybody know if this is still


the same problem in biztalk 2006 (as it is the same error message) or is it


just an error I have made somewhere in my orchestration?? In both cases any


help would be really appreciated!!!
