In 2002, when the Backstreet Boys expressed a strong desire to leave their management company, The Firm, Carter chose to remain with them to manage his solo career. As the group began recording their new album without him, he started working on his first solo album.[9] Now or Never was released on October 29, 2002, and it reached No. 17 on the Billboard 200 and was certified gold, both in the United States and Canada. The lead single, "Help Me" achieved considerable worldwide success while the other single, "I Got You" was a minor hit in Europe while "Do I Have to Cry for You" became popular in the Philippines. The album made the charts in several other countries as well. He also launched a worldwide tour in support of the album.
