I just used the FatCow SimpleScripts auto-install feature for Revolution 2.06 and had the same problem as when doing a manual installation. The Manager brings up a blank screen. When I tried installing Revolution 2.1.1 the Manager would repeatedly bring up the login screen every time I logged in. After a lot of messing around I found the solution was to edit the PHP.ini file (located in the control panel under CGI and Scripted Language Support > PHP Scripting). I changed session.auto_start from 1 to 0. This enabled me to log into the Manager successfully.
