Internet mogul Kim Dotcom says radio station owner Mediaworks has pulled his advertisements.
Dotcom produced a series of radio ads to promote his new Mega file-locker service, which launches on January 20 at a big bash at Dotcom's Coatesville mansion.
The ads were expected to run on Mediaworks' The Edge and other stations from Wednesday.
But Dotcom tweeted today: "Unfortunately Mediaworks pulled the plug on our radio ad campaign :-(."
"Apparently some music labels complained to Mediaworks about our radio ads. Booking of over 500 ad plays terminated. Wow!!!," Dotcom posted.
Dotcom said he was "not blaming Mediaworks".
"They are a great company with great people. It's the music labels that are abusing their power, again," the German national tweeted.
Despite a series of legal victories against the police, Dotcom still faces an extradition hearing next year where authorities will argue he should be forced to face trial in the United States over charges his substantial wealth was obtained by widespread copyright infringement.
Dotcom, and his co-accused who ran the Megaupload site, deny the charges.
The launch of the new site is on the anniversary of Dotcom's arrest.
