How to extend Trail Period

I have downloaded the trail version of Articulate studio in July to present a Business case to start authoring eLearning modules. Initially we thought of purchasing Engage only and later we decided to totally migrate from  captivate to Articulate. Now the trail period is over and i need to prepare samples and present Quizmaker and presenter. Would it be possible to extend the trail for a few more days before we purchase???

This is what i need to present.

1. Different types of Quiz questions in Articulate.
2. Articulate presenter's edge over Captivate.
3. Reporting features... etc..

Any help to extend the trails and to highlight Articulate over Captivate.

Thank you

Kodali.
