Not enough information.

Does it work on your old laptop/PC?
What login information did you use?
Did you forget your pixiv ID / email? What's your ID?
Are you even on http://www.pixiv.net/?
Did you provide the correct e-mail address at http://www.pixiv.net/reminder.php ?

Most likely, you tried to log in using your nickname and it didn't work. Use your pixiv ID or the e-mail you provided when signing up.

Your account still exists:

I don't know how to see your pixiv ID since you haven't uploaded anything.
