14 R1, AWCC AlienFX, won't run

Hello,
I apologize in advance I write in French so the translation can be bad. My problem is as follows I have an Alienware 14 (warranty expired on December 5, 2015).

I can no longer open AWCC? I uninstall it and install it again but I still have the same problem. I have the following message that appears
'' Access to the path 'C: \ Users \ Kevin \ Documents \ AlienFX \ Themes \ Alienware.ath' is denied ''
