Dear Luong,
I am experiencing the very same difficulties while trying to install PlayOnline to my PS2. May you please elaborate how you were able to "trick it into fixing itself?" I am unable to send an e-mail to the PlayOnine tech support without a PlayOnline e-mail address, and I'm afraid that until I retrieve a list of primary AOL access number that is not likely to happen any time soon.
Also, if there are any visiting members to this thread, I am open to ideas, tips, suggestions, and possibly remedies so that I may finally complete the installation process. Your time is very much appreciated.
