I've got the same issues on both a Windows 7 64-bit and a Windows XP 32-bit machine. I've tried installing over 2.0.1 and uninstalling 2.0.1 and doing a new installation of 2.1.0. Once I get it installed, it seems that I can't download profiles over the internet - it just keeps prompting for user name and password. I can download profiles if I'm on the internal network. Once the profile is downloaded, VIA detects that it's connected to a trusted network and seems fine. If I then connect to an external network, VIA attempts to connect and crashes. I've tried exiting out of VIA completely, connect to the external network and then open VIA and it gives the same result - starts to connect and then crashes.
Edit: I should mention that 2.0.1 has been working fairly well. Controller OS is 5.0.3.0.
