Access Denied chords

  			

This is my first tab. I didn't see this song on the web so I decided to try it out.  
Enjoy. Feedback would be appreciated. 

Part 1- This is the first riff that is played. If you listen to the song you can hear  
the strumming. 
e|--------------------------------------------------------------------| 
B|--------------------------------------------------------------------| 
G|-9-------9-------10--------9-------10-------10-------10-------13----| 
D|-9-------9-------10--------9-------10-------10-------10-------13----| 
A|-7-------7--------8--------7--------8--------8--------8-------11----| 
E|--------------------------------------------------------------------| 

Part 2- It has the same sort of strumming as the first riff. 
e|----------------------------------------------------------------------| 
B|----------------------------------------------------------------------| 
G|-9--------9--------13-------10--------9-------9-------10-------13-----| 
D|-9--------9--------13-------10--------9-------9-------10-------13-----| 
A|-7--------7--------11--------8--------7-------7--------8-------11-----| 
E|----------------------------------------------------------------------| 

Part 3- This part is a little bit faster than the first two. 
e|------------------------------------------------------------------| 
B|------------------------------------------------------------------| 
G|-9---9--10--10---9---9---7---7---9---9--10--10---9---9---13---13--| 
D|-9---9--10--10---9---9---7---7---9---9--10--10---9---9---13---13--| 
A|-7---7---8---8---7---7---5---5---7---7---8---8---7---7---11---11--| 
E|------------------------------------------------------------------| 

Part 4- I'm not quite sure about this part, but I believe it goes as follows. 
A.                             B. 
e|-------------------|------------------------| 
B|-------------------|------------------------| 
G|-12-----------12---|---9---10--9--13--------| 
D|-12(let ring)-12---|---9---10--9--13--------| 
A|-10-----------10---|---7---8---7--11--------| 
E|-------------------|------------------------| 

End Part- You can figure out the strumming by listening to the song. I think it is 6x each.

A|-14--12--10--9--|
