MP3 Option cannot be enabled. Digi Please HELP!

Hi. When I try to Bounce in MP3, I get the following error: "The mp3 option cannot be enabled because: Module initialization failed for mp3 bundle. The Mp3 demo period may have expired". But I own the mp3 option license. I bought it from Digistore since day one, actually I never run the demo on this system. I re-checked and synchronized my Ilok on Ilok's site and the license is there as always. My set up is: PT HD2 Pcie, PT 7.3.1 Cs4 and Mac Pro (osx 10.3.9). Any Ideas? Digi support, please help/

Maybe remove the MP3 option from the Applications --> Digidesign --> Codecs folder (do not trash, place it on the desktop), reinstall and hopefully Pro Tools will ask you (when bouncing to mp3) for the response code that you've received a long time ago.

I have no Response code... it's a license on my ILOK, bought recently: Pro Tools MP3 Export - Digidesign - License Never As suspected, I just re-installed the Mp3 Export Option from the PT 7.3 DVD installer and everything back to normal. I hope it's not a chronicle problem. Thx.
