Oh, man, you messed it up. Now, only admins can recover your chars, if you ask here: http://discoverygc.com/forums/showthread.php?tid=97064
You have to post all char names (or one name and ask for a code for ALL ships on that account), and Admins will put a move code on each one, so you can move them to your new account (PREPARE a character which has at least 2 mill cash on it for moving fee).
The first time you launch Launchpad, it should ask to scan for existing accounts, you should say Yes. If you missed that, you should have hit the Scan button in the program, which scans your current account and displays it in the list. You have to Save the list by hitting the Save button. You should make new ones AFTER you scanned and saved your original account. And don't forget to back up your accounts with the Accounts -> Export function.
Now, that you activated your new account, and you don't have the info of the old original one, you won't be able to get it back, as the Launchpad overwrites Windows registry data to switch between accounts. So you'll get into your new account even if you don't use Launchpad to launch the game. And you cannot switch back to your old one, as you lost (did not save and overwrite) the info for that.
Yeah, I know this advice comes late, but it might help you/others in the future. I'm using Launchpad for guite a time now, so feel free to ask.
