Hi, I have a problem with the version 4.8.5, it is terrible unstable in my server CentOS.

The big problem is that the method to come back to a previous version didn’t work (go to a previous version in the update folder and ./update.sh -u (it always works with other versions, but not now with the 4.8.5 and I dont know why)

So where can I download the wowza streaming server version 4.7.6 (the full version, not the update) to do a clean install???

I also sent this question to support, but maybe is faster here.
