My next chance to play with my UACD will be on Tuesday, so it will be a while before then. However, since I just started working with this, I really don't know what problems to look for. The good thing is I am working on my UACD in a Subversion repository so I know exactly what changed at each step of my progress. I have a revision that only has the SP2 integrated into the UACD, and that one installed without interruptions. When Tuesday comes, I'll use the svn tool to check exactly what has been changed to that revision to get the Hotfixes to install. If the request to update the guide was simply ingored, without any reason, then you should keep bugging them. It is unnaceptable keep outdated information in the guide, which so many people read. I thought the guide was a wiki, so people with access to it could edit it... If in my investigation, I find out that qchain is causing that popup it will be even more reason to update the guide.
