MD team claimed that they were going to release MD Pro for sale in June when they were pushing Forex Maximizer. However, I would not take them by their word because for some reason they prefer to use it as a bait for pushing other third party "solutions". Funny thing they also play with different names for MD variations, as they used ForexScalpa (seems MD that is set to trade EURCHF only) with another sales campaign
Shortly, these guys definitely do not put their eggs in one basket and I am sure they do not bet all their money on the MD trading account
As to the license checking you are right, it was FAPT that seemed to have an online checking feature. Though there must be some communication going on because I remember once that the EA displayed that a new update is available.
