faild to execute hgwc

You may have a missing or corrupt file. The best way to correct this is to uninstall CF and then reinstall the client.
I know its time consuming but its the best way to correct missing or corrupt files.

One other thing it might be too , some programs are TSR (terminate and stay resident)in your sys memory ,when you stop useing the program it doesnt dump memory ,xtrap monitors your sys mem activity and if it see`s something in mem it doesnt like it won`t load, what you can try is freeware from download.com or any other site you trust,that will empty your ram ,try this then try to start CF , if it doesnt work ,well it cost you nothing to elimnate this possiblity.
