There has been a lot changes in TC since last build of antag plugins. 64 versions are extensively used now. But there's lack of x64 plugins with proper support of music tags (to be precise, those which exist don't work properly). Your plugin appeared to be pretty good job in the past. Could you, please, consider making new x64 build and/or sharing plugin source via github?
I'm also searching for a audio plugin in TC. Will you be able to bring Anytag for x64 systems?
