Issue regarding custom models

[Quietus]

Hey guys, i'm working on a total conversion with a friend in attempt to expand my portfolio and had a few questions regarding the custom models I've been creating and importing into the level editor;

I'm currently using Maya 2011 student edition. The COLLADA exporter which was recommended by some users on the forum (http://opencollada.org/) didn't recognise Maya on my PC so i resorted to using DAE_FBX export. Everything works fine except for a one issue;

- Despite centering the pivot in maya before exporting, the pivot of the model in the level editor is way off. I'd place an object down and it would appear quite far off screen. This isn't so much an issue with objects like desks or bookcases, but with the tillable wall pieces we are using, it makes aligning them almost impossible. Is there something in the model editor i have to do to change the pivot of the model? Or is it an issue when i export it from maya?

Has anyone else experienced this or has any ideas why it happens?
Many thanks in advance =]
