i got a problem with patching for online,
But when i start the patch is says:
fifa08.exe has located at:
C:\Program Files\EA SPORTS\FIFA 08

i press yes and then it says:
Old file not found. however, a file of the same name has found. no update done sinds file contents do not match

Try patches from other locations.

Is it the right patch for your region ?

Try patches from other locations.
Alternatively, have you modified your CONFIG.DAT in any way?? The patch checks for the existence of fifa08.exe and then modifies just CONFIG.DAT and PC_CL.BIN (the latter being an oddity, as there is a FIFA 07 version of that file copied from the DVD by the installation process), so there really isn't an awful lot to go wrong. Try restoring just those two files from the same location on the DVD and seeing if that helps

If you have a fixed fifa.exe replace it with the original fifa
