hi. i am just trying to get my old indigo g3 iMac 350 working for my kids to use and everything seems to be working fine except that it wont hook up to the net through an ethernet cable. i have done a re-install and i can open either explorer or netscape which works fine but wont allow me access online. i can remember when i was using it that i just plugged it in and it hooked every thing up for me. I have run first aid and get " problem: invalid catalog, 4,0." . checking this out it looks terminal but i cant see why everything else works except allowing me access. any thoughts appreciated.
