I heard that if I have two accounts and they are both active (non-trial) that I can load two clients of EVE on the same computer, is this true?

I tried to do so with two characters on one active account and no go.
I tried to do so with a character on an active account and a character on a trial account and no go either.

But I heard that both of them are loadable if on separate subscription accounts....can anybody confirm this?
It would be quite the incentive to activate my second account.

yes, they need to be on separate active subscriptions.

it works.

Yeah you can only log onto one character per account at a time, you can open as many active subscription accounts as your computer can run, i normally run 2-3, and 1 on my laptop.
