I have been using OpenKore normally BEFORE. But at some point (not sure exactly when it started), my OpenKore files started showing this error:

As you can see with the file details below in the screenshot, this OpenKore I am using right now was recently updated and downloaded (April 24, 2013). I tried downloading again today a fresh copy of OpenKore, but then, the error still exists in my laptop.
But then, when I try it in our desktop, it works perfectly fine.
Help me with this please. I'm quite getting frustrated with this error in my laptop. >.<
Thank you in advance...
