The problem is caused by your invalid conditional comments where you have made three errors
Firstly the htm5 shiv is only given to IE8 and under not IE9. Secondly you missed the closing bracket on the script tag an dplaced a dot there instead. Thirdly the closing conditional comments is currupted also.
This is the correct rule:
<!--[if lt IE 9]>
That should allow IE to work now.:)
