I found a firmware update to install at the PC, with Windows XP/2000, it can be located at this link:
http://co.lgservice.com/index_b2c.jsp
in the first option, you can download the file GSA-H55N 1.05(EW).zip, and the version for this Model.
Before install, pay attention to the readme file, in order to avoid damages.
Good luck, and greetings from Colombia.
