Attempting to burn some napster, buymusic.com, and musicmatch Copy Protected WMA files to AudioCD (yes they are my files / downloaded/used on only this computer ). Even though I still have licenses left to burn... I keep getting C00D11CD errors. Napster gives me errors about being "unable to detect a CD Recordable device." What's strange is I WAS able to burn music with no problems... but something has changed which seems to have broken the CD Burning capability. Here's what've done recently (that I can remember): 1) Installed latest Nero version 6.3. 2) "Winter" Hard Drive cleaning session. Had ~13MB left... delete / uninstalled plenty of old crap I never used. now have over 30GB free on this 120MB HD. 3) Ran RegClean to get rid of some "old junk" left over in my registry. 4) Installed MusicMatch 8.2 (for the music match file downloads). Then when I tried to burn my MM files to audioCD; I noticed the problems with being able to burn. So I started backstepping in hopes of getting it working. Uninstalled MM8.2... no luck. Noticed that IMAPI service wasn't running. Attempted to Start. No Joy. Looked in Event Log / System... notice DCOM error which pointed: The server {520CCA63-51A5-11D3-9144-00104BA11C5E} did not register with DCOM within the required timeout. For more information, see Help and Support Center at [URL]http://go.microsoft.com/fwlink/events.asp[/URL]. Looking in registry noticed that this COM control is: Microsoft IMAPI Disc Master Originally, I couldn't get a "recording tab" in WMP or Explorer. I suspected the "registry clean". Re-imported the "backup" file given by RegClean. So, Now I have the Recording tabs... but I can't enable anymore than one CDR's "Enable CD recording on this drive". Still can't burn to the disk. Tried reinstalling (without uninstalling) WMP9.0; but doesn't help. Tried all the somewhat applicable tips at: [URL]http://www.nwlink.com/~zachd/pss/pss.html#0xc00d11cd[/URL] and [URL]http://www.updatexp.com/c00d11cd-error.html[/URL] Searched through this groups archives; but couldn't find anything which fixes this. Uninstalled CDR devices using Device Mangler. Let Windows redetect; hoping it'd "fix" the problem. Still getting Dcom errors. Not sure where to go... Should I uninstall WMP9? And ReInstall? Will my DRM license be lost? I seem to vaguely remember deleting old ruminants of Adaptec EZ CD Creator from my system during the winter clean session.. I no longer use EZCDC which was broken many moons ago due to a motherboard / system upgrade / XP reinstall. Couldn't uninstall via Add/Remove programs... had to manually delete the directory. Wonders to self if that broke the IMAPI plugin. Any thoughts on how to "restore" a clean installation of IMAPI?
