A new Burning Board license includes 2-years free troubleshooting (3rd part of the version, e.g. 3.1.6 or 3.1.7). New major releases (changes in the 1st or 2nd part, e.g. 4.0.0 or 4.1.0) require an active update access which could be purchased once you buy a license or at any later point of time.
Except for the free troubleshooting mentioned above, you have free access to our forums where you can ask any question concerning the software, but this forum is mainly based upon "customers helping customers". If you want official support (ticket-based) you have to purchase the support option, once again it does not matter if you purchase it now or later.
The V-Collection is a different icon-set for Burning Board 3 (the default one is called "X-Collection"). You might want to take a look at the
Blue Space style, which makes use of the V-Collection icons. You can easily switch back to the default style in the dropdown in the bottom right corner of every page (default style: "Blue Sunrise").
If there's any question left, feel free to ask
