Beta 4 - Install Problem - Music Mod download blocked

[w8nq7HQ4Ph]

I was trying to install Beta 4, and at one point you need to download the Music Mod stuff. Well Windows Live Onecare blocked it and prompted what I want to do. I chose to ALLOW it, but the installer already reported failed attempt and would not let me retry.

I had to install it a second time (without uninstalling), and everything installed properly.

Otherwise, a very nice installer.

Thanks
