@Shirokami07 tweaker doesn't always help. My sis is having problems with the game.. we were able to play one day before her files became borked and wouldn't let her use half her game pad settings.. then when she logged out to reset her game pad and pc to see if it was that.. game just caused an error and wouldn't open at all after that.. She used the tweaker again got it to run its patch and when she opened the game it opened the pso2 launcher and started an update that will only get so far before it errors out. We have literally tried everything for her install and the game just doesn't want to play for her at all.. I on the other hand after a lot of the same trouble shooting was able to have a some what stable experience for about 4 days now or so.. Right now my idea is to try and copy my files that seem to work well over to an external drive and replace hers and see what happens.. cause we are at an impasse as to what we can do to get this damn thing working again..
Basically Tweaker has done well for me but for some reason it isn't working for her..
(just an addition.. her pc is superior to my pc so this is very strange to me)
