Thanks, Krizz. I was hoping that would fix it, but there is something else in there that is being icky and hijacking it back to the 1.18.15e version. Looks like I get to clean install everything, 'cause if I clean-install just POL, upon first launch, it's going to ask me for all of that info anyway. *grumble grumble*
I have a 3rd account that I am almost willing to risk, just to avoid having to reinstall POL, but yeah. Just moved yesterday and have no idea where my physical copies of the game are atm. >.<
I went ahead and entered fake POL info using 'Test' as my member name and squareenix ID and just a string of numbers as my password. It would crash when I tried to use the software keyboard, but enjoyed it when I entered the passwords with the real physical keyboard. I fiddled around with it and got it to a 'check files' thing and it found 2 wrong and is repairing them. Hopefully that will fix it, but I'm not entering any info in until deep virus scan is complete. Even then, it will just be 3rd alt's info that I'm okay with having to do a rollback on. The RMT are probably in full effect with this sort of behavior as they try to gear (gil) up for the new expansion coming out; which I'm sure they think (and it probably will) 'cause a rise in their gil sales.
I hope right now there is a RMT trying to enter the fake info in that I entered and they're hoping they hit a high-roller. ***.
