Made it a little farther by using a zip file posted in another post:
Now, 10 launches have resulted in the following in no specific order:
8 times = Error: Your client is out of date. Please run the patch utility
1 time = EA.com is temporarily unavailable. This may be due to...Please try again later
1 time = I got to account login screen and it told me it couldn't authorize. I tried it over and to no avail.
So, I went to my Net7 game account and changed the password. However, I haven't been able to try it yet because of the above errors. Since I was able to change my pw, it seems unlikely I repeatedly entered the wrong info when trying to login to game account.
