SB Pro PE 4.1 New Features (and stuff) in General Discussion Posted June 14, 2019 1 hour ago, Gibsonm said: Welcome to the forum! Pretty sure this has been answered a bunch of times already however ... 1. Its paid. 2. Normally at some point the cost of 4.023 (the cureent version) is discounted so that 4.023 + cost of upgrade = cost of buying ver 4.1x from scratch, 3. You have two main choices: a. A permanent license (costs more up front, comes with USB stick, valid on whichever machine the USB stick is plugged into [or a shared IP address]). b. A Time based license (initially cheaper, includes upgrades, limited to the one machine you bought it for [and can be impacted by motherboard upgrades on that machine, etc.]). Details here: https://www.esimgames.com/?page_id=1530 Be aware that there will be an opportunity to pre-order the upgrade (if you decide to buy 4.023 now) and buy the upgrade at a discounted price - the timing of that is currently TBA, but will probably be announced here and reflected in the page that I linked. Thank you for your patience and answer, very helpful to me.
