I agree with wibble and your tclient.conf shows that you should be already using one of the emuproxys.

Try 'ps ax | grep Proxy' without the quotes to see which proxy is loaded

Also also show the contents of your /etc/sysinit.conf (if it exists).

If it doesn't exist, then show your /etc/dflt_sysinit.conf file.

Which ISP are you with?
