Hi. Your serial number will work for older versions of RM. If I recall, version 2.51 of Replay Music used gracenet to identify track info. Starting with version 3.20, Applian started using a different search engine for finding song, artist and album information. My experience has been that since making that change, RM is not as efficient in labeling the recorded music. I would love to get my system back to the way it worked back when I first got RM. So far, even with uninstalling RM 3 and reinstalling 2.51, I still have less success with track labeling. It could be that some parts of RM 3 are not gone and are interfering with the track look-up function. Does anyone have any tips on how to fix this problem? ----- Original Message ----- From: Life My Way To: blindreplay@xxxxxxxxxxxxx Sent: Friday, January 22, 2010 8:33 AM Subject: [blindreplay] replay music. If i own the most current version of replay music, and wish to try the old versions may I do so with the serial i have? does the serial cover old versions of replay music. from what i am hearing the old versions of replay music grab song data better then the newer versions? thanks for your help on this matter.
