Hi Tc,

I don´t know if you use different Serials for each computer.

But Impulse allowes you to install the games on as many computer as you like.

The only restrictions is, you are only allowed to play the game on one computer at a time.

Means, same Key used for Laptop and Desktop, not allowed, but even when you use the same key or account on both comps, you also should

be able to download and install Entrenchment.

Greetings Ed

P.S.: Just click on the Impulse Orb, Register for Product and add Entrenchment to your Laptop-Impulse. Than you should be able to download it.

TcDohl & aodwildcat,

this sounds like you may have 2 accounts, one with the base game of Sin's and the other having the expansion Entrenchment. If so, we need to merge the accounts back together, please e-mail us at support@stardock.com and give us as much info as you can, serial numbers are a good start.
