It would have been more obvious if you would've posted a screenshot of what it was supposed to look like and what you were getting instead of me doing all the work.
With that said fill in your system specs it would be more helpful to
System Info - See Your System Specs
I downloaded and installed that theme and it worked fine for me being you said you have trouble with other themes doing the same thing you obviously have something else wrong try running Option 2 of this tutorial
SFC /SCANNOW Command - System File Checker it will not harm any data or programs you have on your computer it will change any .dll you have changed back to the original and also if you use that universal theme patcher you'll have to re-patch your files again.
