After the work done to the site yesterday I cannot launch the item collector. I am using Windows 10, so I had to download a non-packaged version of WinPcap. "An error occured while downloading an update, please try again later." This is when running as administrator, and I downloaded the most recent backend.exe and backend.md5 from the github repository.
The item collector hasn't been patched for the last game update so it won't work. I'll look into the downloading issue though.
