I just installed a Wireless-G PCI Adapter with SpeedBooster (model WMP54GS, driver verson 18.104.22.168) on a Dell Dimension E510 running Windows XP Pro. The computer was working fine, but after the installation of this card I now get the following error during start-up just before the desktop appears: Linksys Wireless Network Monitor Access violation at address "some-hex-address" in module "WMP54Gv4.exe". The memory referenced at "some-hex-address" could not be read. And on shut-down I get the following error: PCARmDrv.exe - Application Error The application failed to initialize properly "some-hex-address". Click OK to terminate the applicatoin.
