I cannot help you to fix the problem.... im not an aruba employee...
I work for a partner... and if you do you should have a Country Manager which can give you the contact of your Sales operations guy or girl... they are the ones that can give you access to the airwaves demo....
You can also install airwaves in a server with a demo license but then you need again the sales operations guy to give you access to generate demo keys...
Thats everything i can do for you which is pointing the person that can help you...
I belaives you are a partner right?
In what area are you? if you are in my area i can tell you the name of the sales operations of my area... my area is LATAM...
Cheers
Carlos
