WordPress.com blog won’t import php5.ini modification

I tried to import my wordpress.com blog into my own wordpress.org installed on my own servers.
I exported and xml file and imported it.
It starts working and stopped after about 20 seconds instead of finish working.

I have a php5.ini file in the root folder of my server (I use godaddy) that goes like this:

register_globals = off
allow_url_fopen = off

expose_php = Off
max_input_time = 9999999
mysql.connect_timeout = 9999999
max_execution_time = 999999999
set_time_limit = 999999999
memory_limit = 16M
upload_max_filesize = 50M
post_max_size = 50M
variables_order = "EGPCS"
extension_dir = ./
upload_tmp_dir = /tmp
precision = 12
SMTP = relay-hosting.secureserver.net
url_rewriter.tags = "a=href,area=href,frame=src,input=src,form=,fieldset="

[Zend]
zend_extension=/usr/local/zo/ZendExtensionManager.so
zend_extension=/usr/local/zo/4_3/ZendOptimizer.so

I know that the php5.ini does work because when I’m on the import page it says “max file 50mb”.

I want it to import – please help.
