When the DRM license database gets corrupted no new DRM licenses can be added to the phone, frequent around firmware updates
The only way to solve this is the reformat the phone. You may also need to reformat the memory card (or at least I did).
This is exactly why I was criticizing my network operator Telenor when I was in a pilot project testing their different services.
They offered different subscriptions and online purchase solutions such as streaming TV over 3G and a music store.
As Mr. Rafe mentioned the licenses is stored into the phone memory and as I was handed a N73 by my operator to test their survices a fw update meant that I lost all my license. (Besides restoring a backup successfully was almost impossible in the early days of the N73)
What was more crucial was that the license didn't get to update itself successfully.
To make matters worse you could only listen to the music a total number of 999 times.
They did offer download of the same songs onto your computer. Here they decided to use DRM'ed .wma files which again meant that only one computer could play the tracks and that license of the song had to be downloaded each at a time. (Also here the amount of times it could be played was 999)
As a test pilot I of course submitted my report back to them regarding these issues and explained that it was totally ridiculous. And I'm glad they listened to me. (Mostly because I was probably the most tech-savy of the participants)
When they finally launched their music service they decided to get rid of the DRM in the music, however the quality was further reduced (both because of long download times, copyright and the removal of DRM)
They still offer the same tracks for your pc and now they use unprotected .aac files for the phone download and .mp3 files for the computer download.
Which I think is fine.
What really surprised me was that the tracks I downloaded as a test pilot still is there available for me to download even this day, both as a computer download and a mobile download.
They even got rid of the whole DRM system of all the tracks I previously had downloaded.
Good to see that they've understood the future.
The biggest issue of it all is the label companies that haven't understood the future yet and all the DRM exists because of them.
I don't mean that DRM is necessary a complete bad thing, but heavy DRM is.
Examples are Spore and Apple's DRM (now finally removed).
The only form of DRM that I support is watermarking of digital medias.
(And yes, I even hate the region restrictions of my purchased DVD's)
And as Mr. Steve mentioned it only harms the legal consumers as other users can benefit from totally unprotected medias.
