After a short while the box where the servers should be listed is spammed with a JSON error.
The attached screenshot is from the previous version, but I still have the problem in the updated version.Download Failed: Couldn't parse the response as JSON.
*EDIT*
It also seems to happen when it tries to refresh. This time I scrolled to the bottom of the error.
