I would say you didnt load everything to the server. and I can not diagnose without access to admincp and ftp so I can fix what it is you did. Either you can pm me the info to what I just posted or uninstall it and retry and read all the directions.
As far as trust worthy I have fixed several members here's sites and I have 4 of my own and dont really give a rats butt about another site..your choice.
