After launching Proclaim today (Mac, 10.6.8, 2.4 Core 2 Duo, 8GB RAM), it downloaded the new update and asked me to install and relaunch. I clicked the button and waited, and waited, and waited. Looking at the activity monitor revealed that the Proclaim process was sitting at 75% CPU usage, but the program wasn't launching. After waiting a while longer I finally did a force quit on the process and tried to relaunch Proclaim. Same issue - the process would spin up to 75% CPU usage, but the program would never launch.
I checked the log files, but nothing was being recorded (which is why they aren't attached). I then downloaded the installer from proclaimonline.com and installed over the top of my original Proclaim installation. Same problem. Then I deleted Proclaim and installed fresh. Same problem. Then I deleted the Library > Application Support > Proclaim folder as well as the Proclaim app and installed fresh. Same problem.
Anyone else seeing this behavior or have any suggestions? Thanks!

UPDATE: Just realized I didn't try to most obvious troubleshooting step of all - reboot and retry. So I did, and still no go. Oh well.
