Hi all! This is my first thread and please excuse my lack of expertise in this area. I've recently opened up an external DVD writer (a GSA-H10N JL10 internally) to put into my desktop, and I wanted to experiment with the hacked JJ11 firmware by tdb that was so highly regarded here. However, when I tried to run the executable, I get an invalid argument error message, and the updater shows up with no text. I then downloaded the JL11 firmware from the LG website to test, and that didn't have any problems. My computer is running on Vista Ultimate x64 and I wonder if that have anything to do with it? Any help would be appreciated.
