Activation limit exceeded !!!! - What Gives?

[Old-Banger]

Looks like I am heading down this road.

Just the one install from new (dvd version) on my PC using Win7 64bit.
No hardware changes at all, tried to run game earlier it asked for re-activation. I did so, played for a while whilst connected to the internet.

Fired up the computer again just now for another session offline, it asked for re-activation again. I have made absolutely no changes to my system!

Prior to today, it has been run many times with no such issue.

So, 2 re-activations down, presumably 1 left then I cannot use my software for a month. Great. I shall email Solidshield, but I am not hopeful. No doubt they will blame anything but their own software (even if it proves to be the case that it is at fault).
