Hello, I have a problem with sidebar–it does not work. First, I installed it according to instructions on http://www.win2008r2workstation.com/win2008r2/sidebar, and it worked. But than I had to reinstall Win 2008 R2 once again, and now sidebar does not work anymore. It does not start at all. I reinstalled it according to instructions, all files were copied etc., but it does not work.
In fact I cannot reinstall boot screen and login screens either: even copying files manually does not work. Apparently I have Win7 files in System32 folder and other, but still the usual Win 2008 R2 login screen appears. I do not now what happened. Themes fortunately work.
