First of all, no its not matter of Joomla instalation.
You have to find another server host (maybe free, but i suggest you to pay for one, it doesnt cost much and it gives you much enaugh). Then after you install Joomla like that i had seen that you didnt change files writable to 777 (called CHMOD).
List of files to change CHMOD is in your installation.
Im pretty sure that this is host problem.
