I don't get it. I load my axim x30 and it becomes unstable.

I am trying to use spb pocket plus and pocket informant along with a free firewall (http://www.airscanner.com/downloads/...l.htm#overview

The system just goes to hell once these 3 things are loaded....
PS- I got my axim 4+ months ago and never did an upgrade. Is this necessary? Anyone know how to tell?
anyone know a solution?
Thanks

How does it run wirh the airscanner firewall unloaded? I had that firewall on my x50 and whenever it was loaded it dogged the system down horribly.
