"I don't know if I am doing something wrong, but I was never able to get this application to run. when I start it, it freezes for a very very long time (like 20min) during which it becomes completely unresponsive and unusable. Any attempt to initiate a command would bring the "this application is unresponsive" telling me to click yes to close it. Is anyone else having this issue or is this just me?"
i think i know what is your problem, you set your limit to -1, meaning you want calls back from the day you first started using the phone (or flashed it) let it run for a while (maybe couple of hours even) till it loads it, go to settings and change it to like 30-60 days you dont need more than that
