Chanalyzer 3.1 inSSIDer crash software fix

I received my WiSpy 2.4 yesterday, very neat, and I planned to get stuck into some fault-finding. Unfortunately I found that the Chanalyzer 3.1 software crashed whenever I tried to use my WiFi card. I tried inSSIDer, with the same result. I then tried changing from my laptop's internal WiFi to an Orinoco PCMCIA card. Still it crashed. I tried a SanDisk PCMCIA, same result. Then a GigaByte USB-stick WiFi, and finally it worked! But it clashed with the WiSpy for USB space.
