Error raised when trying to read from watch file if you still have the old watch file.

When I tried to open my watch list in the most recent version, the following error was thrown:

I figured it was because the old file was a pickle file and it was trying to decode it as a json file, so I deleted the old file (AppData > Roaming > anime downloader on Windows) and voila, it works.

Is there a way we can identify and delete the old watch file automatically so that people don’t have to do this on their own?

@Enderlein Even though you have push access to the repository, it’s better to open a PR, unless it’s a very minor change. I’ll do the same too, because another pair of eyes is always better.

Haha. Okay then.
