I checked the link, for some reason the ftp site doesn't like me linking into folders I guess. I updated the post but just go to
ftp://up.ppcgeeks.com then Titan then Users
I have never used titanunlocker.exe so I cannot say on that one. if you can successfully get olipro 2.40 on your phone, just use that, then after you get your custom rom on it, install nueSPL if you are having too many issues installing it first.
