By using new version of drmdbg (up to drmdbg1113), the key (KID and SID) info will be created automatically in your desktop. No need to paste from clipboard and no need to create key files manually anymore.
In your desktop a new folder name 'drm2' contain 'drm2-i.key' will be created containing all of your entire protected movies/musics's kid and sid in one file. What you need to do only drag and drop your files to drm2wmv_e, a new file will be created (copied from original) without re-encode them with new filename start with [NoDRM]-yourmoviesfilename.wmv or [NoDRM-yourmusicfilename.wma

Best Luck.
