How many activations do I get?
You can indefinitely activate your copy of the game on the same PC. You start with three activations (so, three different PC hardware configurations) to begin with. After one month, one activation will be re-credited (up to a maximum of three available activations at any given time).

After one month, one activation will be re-credited (up to a maximum of three available activations...) <--Is it me or is this saying, indirectly of course, that you will be "activating" your installation on what appears to be a 1-3 months cycle?

You can indefinitely active your copy of the game on the same PC. <--This also points to the fact that you will be "activating" your copy regularly.

Ubi? 1C?

No simace, don't start reading between the lines.
You must activate each installation, this activation is a file on your pc and works only with this hardwareconstellation.
You get 3 activation files in the first month, and you can get one additional file each new month.
The files are working until they are deleted.
There should be only 3 active activation files, so i assume you have to uninstall one of your three installations to be eglible for a new activation - file.
Thats what i read.
