Mijoshop downloads going to 'file not found http://*/index.php/*/account/download/download?order_download_id=*

Here's the Issue.  I have Joomla 3.2.0 installed with Mijoshop 2.2.1

When my customers order downloads after clicking on the download box I then get the following message



file not found http://*/index.php/*/account/download/download?order_download_id=*

After some testing it is apparent that when I set up a small download then this was fine.  The breaking point being at about 120MB before it stops working.

After some research I found this post http://forum.opencart.com/viewtopic.php?t=3310 . This is our PHP Info http://www.rubydance.com.au/rdtst/phpinfo.php  

which is for Open Cart. 

so I added these values to the php.ini

upload_max_filesize = 390M ;
post_max_size = 400M ;
memory_limit = 640M ;
max_input_time = 3600;

This didn't work but with some help from my hosts HeartInternet  they suggested adding this to .htaccess

RLimitMem max

The downloads now work on the installations.
