Hi, have to get any warnings before installation/ joomal server checkings / ?
Have to got there .httaccess - if yes, please rename.
You can also try to install standard Joomla 3.1 (not our quickstart) to check if it's problem with server or not.
But I'm sure that QS works because I have installed it few times, also our clients didn't have problems.
Joomla 3.x have high requirements !
