I am Having the same error message. The script installed for me, however I still can't change and of the tag info on some my mp3s. It is just in one folder and some of the files are fine but the ones that had a long album names got truncated. I used the tag editor suggested and changed the files there and sved them. Looked back under explorer and the info was missing all I have is the title. Mp3s still play. Some of the files can be changed, the ones that already show the tag info. I noticed when I go to properties/security of one of the corrupt file entry it says full control for me/user, System and Adminstrators. Under the name WMPNetworkSvc it shows only read. Could that be my problem? If so how do I change it.
