Aung San Suu Kyi was released from house arrest in November following Burma's first election in 20 years.
The NLD was officially dissolved for refusing to register for the poll.
This first official warning was made in a letter to Aung San Suu Kyi and the chairman of the NLD, Aung Shwe, says BBC News.
A possible tour of Myanmar by pro-democracy leader Aung San Suu Kyi could cause riots, state media warned on Wednesday, implying she would be responsible for her own safety.
Nobel Peace Prize laureate Suu Kyi is planning her first trip outside the former capital Yangon since she was freed from home detention last year just after elections to end army rule.
