OK, I was editing an audacity file (2.0.1 windows), but the lights go off. Now everytime I open it, the tracks are gone, appear a message of “Error: mismatched tag en línea 627” (I use audacity in Spanish). Here a video showing it:
This file should open, but it will say that “e999999b.au” is missing and it will appear as silence in the waveform. In the error dialogue, choose the option to treat missing audio as silence for this session.
I can’t tell you what the correct name of the file is, or if it actually exists. If you can find it in the “audio vos real_data” folder, then you can rename it to “e999999b.au” (without quotes) , close and reopen the project, then Audacity will see the file and the silence should disappear.
