It’s more than four years ago, AFP-Lookup 1.x (Standard) has reached end of life now: Last release with version number 1.9.9 was published on 2012/01/28.
Our other still active products AFP-Lookup 2.x (Professional) and AFP-Lookup 3.x (Complete) have shown an enormeous growth since then, with raising costs for development and maintenance. We’ve decided to remove upgrade option from 1.x to one of the more actual versions from April, 1st. 2016 on.
If you think about upgrading your old 1.x licenses for a while already, NOW is the right time to do this!
