Website Suspended due to excessive server memory use

Hi,

Last month i online my zen cart website. In less then one month my hosting company suspended my website with the following email:

"The scripts in your website has severally damaged our services on server due to memory abuse. Please let us know when you are ready for backup".

I don't change any code in zen cart, then why this happen. Currently i have only one customer (myself) registered on zen cart. The hosting company does'nt provide me any proof with that.

I take backup of database. What can i do now??

Thanks,

Strong Man

find a server with more than a celeron 1.2 and 512 mb ram....

Zen Cart is an intensive program but if you caused serious damage to their servers with a non modded store and no traffic, that tells me that their hardware is not up to the task of anything higher than simple html
