Neutrideo Hi, sorry for this late reply.
I registered an account with your host and have been testing things to see if it is possible to make it work.
Alas, I can not. The server forces timeout on php scripts, so composer times out before it can even start. Additionally, I can't get php to assign more then 79MB of memory, even though the phpinfo states 150. Composer need 1G to work comfortably.
I am really sorry I could not make it work :/
