Free2me error : Enter SID for this file

[Bilskate]

Hi I got this message when I try to use Free2me, of course I have the licence for the file and I can listen to it on Windows Media Player. But I can't decrypt it with Free2me, because I got this message "Enter SID for this File".
It there a way to find the SID for the file on a folder on my computer ? Or what can I do ?

Thanks.

Have you extracted licence keys with drmdbg?

Have you read how to use freeme2?
