Network crashes when a B.Net download is happening

I much prefer the older B Net app. The social tab combined with the entire window is much more fluid. Also, the new B Net app is causing my ENTIRE NETWORK to crash when installing games. I have multiple computers and the issue seems to be the case with all of them. I have verified that this is not just an issue on my network, as my other friends (more than 5 people) all have let me know that they are having the same issue. The entire network crashes until the download or update is paused and then resumed later. Sometimes the download works and doesn’t crash the network, but most of the time it does. How can I revert back to the old B Net Desktop App that didn’t have problems? I much prefered it as it worked nicely without bugs and the social window was combined.
