There shouldn't be any OS dependency, browser yes.
I see you are still running version 2.2.0, back in version 2.3.1 I patched the steelseries library (updated to v0.14.3) that fixed some script exceptions in later versions of FF (v21+) and Chrome (and possibly other browsers as they updated an old canvas API). I'd suggest you start there.
The only odd thing is your page loads OK for me in Chrome 30, FF 24, and IE 10.
