M&B Defragmentation Leads To Choppy Graphics? (Need Help)

[Skrubb]

Hey Guys!
Skrubbin Here
I turned on my computer this morning and Steam asked me to Defragment my Mount & Blade: Warband game for better perfromance.
So I did...
It tooks literally half a second and then says Defrag complete.
Then I start it up and it notifies me once that the Game can't find dvx 9 and crashed.
I tried starting it up again then it loaded..
However now in game my graphic settings are on the same as before but very choppy.
I tried uninstalling and reinstalling without any positive result.
Hopefully somebody out there knows the solution.
I would appreciate any insight onto the subject...

Thank you guys :]

Steam Library
Right Game > Properties
Local FIles Tab > verify integrity

its possible in the defrag a file was damaged.  also use this to remove steam games to truely uninstall

make sure you have around 10-15% free space on your hard drive and do a real complete hard drive fragmentation....do this BEFORE  a reinstall of the game
