Secondary CoCo and Mask Problem in Trial Version?

I have been playing around with Adobe Premiere Pro CC 2014 for 15 days.

Buying a license after 30 days was my plan, however the secondary color correction doesn't seem to work.

Indeed the Mask function doesn't work and I tried with RGB and three way color correction.

Is it the limitation of the trial version?

I just hope that when buying a license I will have access to the mask function.

Another problem is the tonal range that doesn't seem to work in Three way colour correction.

I am using a Macbook Pro 2014, 2.6 Ghz I5, 8GB 1600Mhz DDR3, OS 10.9.4

My question is : Did adobe lock some functions in the trial software?

Thanks

GG.
