trial license for "caching feature"

We previously contacted you regarding caching feature in Unity3d, but we have more detailed questions for you.

  1. First of all, we would like to know how to access trial license for “caching feature”.

  2. Do we have to manually define the version number in “int(integer type)” when using “LoadFromCacheOrDownload(url, version)”?
    Or is there a way to manage files by comparing created date or size etc.? We would like to know if there is a better way to do it.

Dear sir(s),

Thank you much for contacting us, however I believe you to be utterly confused.

This is a public support forum. We are legion, but it is not within our powers to grant you a trial license for anything. I suggest you email support@unity3d.com instead.

When you download Unity, install and it comes up with the licensing panel, go through that and select the 30 day trial. After 30 days it’ll revert to the free version.
