I installed freelauncher with a card reader. also, u can extract directly to the smc drive, it puts al the folders etc in the right place automatically.
....I could be wrong but are you sure you didn't install it with pclink then copy the freelauncher from smc to PC, then copied back over again - I thought pclink encodes the file to your gp32's id....
i registered my gp with gamepark and entware with the usb. after that all the stuff u download/buy from them is registered to ur gp, so u can just install it with the card reader.
