I am also having this freezing problem. I just purchased 2 licenses, unfortunately the software is not useable. I am excited for a fix for this, because I got a little teaser and really like it.

I have two instances running on two seperate machines. One machine is a laptop with vista 64 bit(laptop_stats) and one is a desktop with XP, the desktop is older(desktop_stats). I can connect fine, I have my do not pass setup as a whitelist to only allow 3 keys or so.

For me the crashes seem to be more frequent, i can connect the machines together and keys get passed but after 5-10 minutes one client crashes on one machine and I have to kill it via task manager as others do.

Hope this helps, I am willing to send any info you need, I'd love to see this resolved. Thanks, and keep up the good work - this product is really cool!
