I believe the problem your having is a time out issue. You might need to up your max execution time and max input time.

Change it to something like.

max_execution_time = 300
max_input_time = 90
hope it works for you - as you know smoke I was unable to change the settings in .htaccess so I'm not sure if that is the fix but I sure hope it is for everyone elses sake.. any further pointers would rule//
