Surely you're paying maintenance on the licence, which entitles you to support from your registered support provider?
DSXchange does not exist as a substitute for proper support. Your support provider is (or needs to be) aware of the particular issues at your site, what patches have been installed, and so on. We on DSXchange obviously can not be thus aware.
