Wireless network card disappeared overnight?!??!?

Hi, everything was working fine yesterday. But now my wireless seems to have completely disappeared. The router works fine, it's just that my computer isn't recognizing the internal wireless card.I have an Inspiron 4150 and the TrueMobile 1150 client manager says "no wireless network card present. No communication possible." The Device Manager seems to think that I have new hardware installed - PCMCIA UNKNOWN_MANUFACTURER - and says the drivers for the device are not installed.  I've tried downloading the TrueMobile 1150 driver off the website but it won't install. I've been trying to figure this out for hours now. HELP!
