fyi - I now know what aERonAUtical96 was talking about when he mentioned the "=" when taking some screenshots.
Anyhow, also wanted to let you know that your corrupted file also contained a lot of blank spaces at the end of the file which means that the software set up all those blank spaces for codes from vixen, but it seems the save got screwed up at some point and left out a lot of data. I hope I was able to recover everything. If not sorry.
Screenshot 1:
Shows a comparison between your corrupted file to a good file. Notice that your file doesn't have the openning tag of <channels> and of course all your 512 listed channels.
Screenshot 2:
Shows a comparison between your corrupted file to a good file. Notice at the end of your file there are no closing tags and it is showing a lot of blank spaces, while the good file has all the closing tags and no additional spaces afterwards.
Hope this helps anyone else.
