1. If you have purchased EaseUS Partition Master 9.x.x (9.2.2 not included), contact support@partition-tool.com to get a serial number and the WinPE setup file. If you purchase EaseUS Partition Master after version 9.2.2 is released, go to step 2.

I can't say anything about EaseUS. I don't know them -- have never dealt with them as a customer -- have never posted anything in their forums etc. I would think it reasonable if their sales dept. got an OK for X number of activations, & I would think it reasonable if their tech folks set the activation server to only work up to that number -- the trial & the GOTD seem identical, & they don't want people using that serial number for the next several days, weeks, months. In that scenario they simply guessed too low with the number of activations.
