Please help me center Livezilla chat buttons

I've been trying to figure out how to centre/move up and down the Livezilla chat buttons.

I've tried on two themes, defualt and cleaner by defualt - 2 column.

I've attached screenshots how the buttons look in both themes, I just cant figure out how to move the button, up/down/left or right.

Any help would be very much appreciated.

Thank you in advance.

If you send me a link to your site I might be able to tell you how to modify your css to achieve that.

Thanks to Justinv I mangaed to centre the button.

Changed:
<div style="text-align:center;width:145px;">


To:
<div style="text-align:center;">
