Access Key Question

My question is if I installed Factions and Nightfall on my husband's computer, but now I want it on my computer, do I have to uninstall Factions and Nightfall off of his computer in order to use the access key on mines? (sorry such a long sentence hehe)

Access keys are tied to the account used to make it.

The client (on the CD's) you can install anywhere.

You can use your account anywhere there is a client.

An access key can only be used once, for one account. Once only, no more.

So no uninstalling needed, just the account information.

Thanks alot!
