Multiple Accounts

If u have a 2nd copy of the game, is it possible to create a 2nd (new) account on the same pc that the 1st copy has been installed on? I ask as I would like to be able to play all 6 types of character but only have one pc avail to me. Am somewhat nervous of this as I do not want to lose the 4 charaters I have already built up.

Yes, you won't lose anything at all.

You can only be logged in one account at one time. Your account is online, it's not tied to your pc in anyway.

Many thanks, have done it and works with no problems.
