I have Exisiting DRMed media files DRMed with WMRM 7. I'm trying to make them available for Download using WMRM 10.1.2. While making it available for download the header info like license acquisition URL is changed. Care is also taken that the keys(private key, public key, seed) used during protecting the media file are used while downloading and sending license response. But as sson as the license is acquired which I see in a non-silent mode, i get an error "Unable to obtain license". I've run and debugged the file in localhost configuration as well which shows me that license is acquired by windows media player, yet it gives the error of "Unable to obtain license". I suspect the cross compatibility of WMRMs used. Can anyone suggest me of the cause of the issue and any measures for prevention/solution.
I've found the solution. The issue is not about cross compatibility of versions of WMRM. The solution was to add revocation data to the response i.e. revoke previous license versions.
