I've noticed that from all of the online videos of Flexi 10 Pro (fully activated) involved the 10.0.1 (build 1577) versions, and not the newer 10.0.3. I would think that this is why SAi came back with a FREE update from build 1577 and 1604 to 1688, and now only offer version 10.0.3 for download to possibly eliminate the activation method used. It is almost impossible to find a downloadable version of the 10.0.1 (build 1577) anywheres. Good thing that I have it. Does anyone have an idea as to how to crack this puppy?
