I would like to buy a licence for one month. This is a small project and it only runs for a week. I don't have the budget to pay for a whole year. Is it possible to buy a month. I have contacted the help desk several times for weeks about this now and have not gotten a response. I want to launch the project in two days now. please will you let me purchase one month. Is there a number I can phone to chat to someone? I'm at a loss of how to speak to someone from vuforia about this.
