"Failed to create low level event hook"

[GoogleCodeExporter]

So, I wanted to use this library for an APM-Meter. It worked fine at first, but 
then I got the following:

org.jnativehook.NativeHookException: Failed to create low level event hook
    at org.jnativehook.GlobalScreen.registerNativeHook(Native Method)

I do not know what caused this, but it appeared after I built my project into 
the jar and now appears independently of running it from the IDE (IntelliJ IDEA 
12.1.3) or from the .jar file. I am using version 1.1.4 of this library on Win7 
64-bit.

Sometimes, it doesn't throw an exception, but instead just does nothing.

Ok, worked fine today, even after starting it from the .jar and the IDE several 
times. So reproducing will be pretty hard to impossible for this one =(

That error only occurs when SetWindowsHookEx() returns null.  There isn't a 
whole lot of documentation that outlines why that may occur, but I will add in 
some more detailed information to the exception in version 1.1.5.

This should be resolved as of 1.2.0-Beta1.  I have added GetLastError() to the 
error logger to get more information in case this happens again.

I just got the same error without a clear reason. It just started throwing this 
error after maybe 20 to 30 runs. I am using version 2.0.1.
