Fans looking to score tickets to the city's biggest pop culture fest encountered online Kryptonite Wednesday.

The site for the New York Comic Con tickets experienced severe technical difficulties during the first day of sales for the show that takes place between Oct. 8-11 at the Jacob Javits Convention Center.

ReedPop, which organizes the annual event, said it was working with the ticketing vendor Show Clix, to get the system back in order.

"We apologize for this failure, we too are frustrated, disappointed and know our fans deserve better," ReedPop said in a statement.

The tickets range from $40 for one-day passes to $105 for four-day passes. The $75 three-day passes sold out Wednesday.

The convention, which features panels from comic book writers, artists and includes previews from hit movies and TV shows, has grown in popularity since it launched in NYC in 2006. Last year's event saw 151,000 people attend during the course of the weekend.
