I'm in the same boat, for the second time. Last time I went through and deleted everything folder by folder skipping all the files that I was unable to remove, restarted, and was able to reinstall. I'm not doing this again. I want so badly to love this game, but this is ridiculous. It's been such a long wait for those of us in the West, and this is what we're getting?
I just want to fall in love with PSO again, but damn they're determined to make me give up, and I'm certainly not putting any money into a game I can't even consistently open.
