How do I determine the name of the PC that has full access to the files in my SkyDrive account?  My PC required a new hard drive, and in the process produced (apparently) a different computer name.  The files that were stored with the previous name no longer can be deleted.  There's simply no option to do so.  But I do not see anything in SkyDrive that tells me the name of the PC which stored the files.  I'm willing to zap my entire SkyDrive storage and start again, but I don't see anyway to do even this.  Plus, my SkyDrive is now full.  Very frustrating.
