I did a lot of work tagging my files with v3.06a. As a final step on the files I use in the car I ran mp3gain which added APEv2 tags to everything. Everything worked fine.
I finally made my trip to Ireland and copied my files here. I also upgraded Mp3tag on my computer here to the latest version. I read in my files and a bunch of info is missing in Mp3tag. Like virtually everything. Artist, Title, and Album, for example.
Using TeamViewer I logged back into my computer in the States, brought up Mp3Tag v3.06a on it and looked at the same files. All of the album/artist/etc information was there. I copied a few files that I could see were working there over to my computer in Ireland. Same issue -- except one file did have all of the info properly displayed and that one did not have the APEv2 tag (hence my suspicion). I opened the files I brought with me with foobar2000 on the computer here and lo and behold all of the data is displayed exactly as expected. I am running Win 7 in the States and Win 8 here in Ireland.
Anyone else see something like this? Maybe I fat-fingered something but I don't see what. I have Mp3tag options set to read all tags, including APE. Thanks!
